of bugs in which the interrupt thread could be preempted by an IPI,
indefinitely delaying acknowledgement of the interrupt to the PIC, causing
interrupt starvation and hangs.

allow for connection load balancing across interfaces. Currently
the address alias handling method is colliding with the ECMP code.
For example, when two interfaces are configured on the same prefix,
only one prefix route is installed. So connection load balancing
among the available interfaces is not possible.
The other advantage of ECMP is for failover. The issue with the
current code, is that the interface link-state is not reflected
in the route entry. For example, if there are two interfaces on
the same prefix, the cable on one interface is unplugged, new and
existing connections should switch over to the other interface.
This is not done today and packets go into a black hole.
Also, there is a small bug in the kernel where deleting ECMP routes
in the userland will always return an error even though the command
is successfully executed.

pmc_flush_logfile is now non-blocking and just ask the kernel
to shutdown the file. From that point, no more data is
accepted by the log thread and when the last buffer is flushed
the file is closed.
This will remove a deadlock between pmcstat asking for
flush while it cannot flush the pipe itself.

These expansions, which were already in the Bourne shell, work correctly for
the most part. The testcases are only about the parts that already work
correctly.
We'll start noticing this with the next flag introduced as the lower
32bit are all used.
As this is old code we might need to do a full tree sweep one day, unless
changing our strategy to use a different `API' for getting/setting flags
along with the rest of the statfs data.
While here compare to 0 explicitly [1].

They are mainly about expansions in here documents but because all the
testcases are in $() command substitution, we also test that $() command
substitution is recursively parsed (or very close to it).

On Linux, /proc/<pid>/fd is comparable to fdescfs, where it allows you
to inspect the file descriptors used by each process. Glibc's ttyname()
works by performing a readlink() on these nodes, since all nodes in this
directory are symlinks.
It is a bit hard to implement this in linprocfs right now, so I am not
going to bother. Add a way to make ttyname(3) work, by adding a
/proc/<pid>/fd symlink, which points to /dev/fd only if the calling
process matches. When fdescfs is mounted, this will cause the
readlink() in ttyname() to fail, causing it to fall back on manually
finding a matching node in /dev.

- Remove dosansi, pc and pc3. I suspect nobody ever needs these.
- Add vt100, screen and xterm-color.
This file is now probably more than sufficient in most cases, even for
common use outside single user mode, where people just use the console
driver, a graphical terminal emulator and a terminal multiplexer.
Right now we have a termcap.small in the tree, but we don't install it.
If we do install this file by default, it is more likely for
applications to work in single user mode.
I am not entirely happy with the contents of this file. In my opinion we
should remove the `dosansi', `pc' and `pc3' entries and replace them
with `vt100' in case someone uses a serial console.
The file does already have entries for `cons25' and `xterm', which is
used most often.

or overflow the netisr queue and fall back to the interface
queue so that we can garuantee that the ifnet pointer stays
valid. Formerly we ended up with reference counts <= 0 in
case the netisr had returned ENOBUFS. The idea is to track
any packet in the netisr queue and only change the refount
on edge operations for the fallback interface queue. This
also avoids problems in case the if_snd.ifq_len lies to us.
Also rework refount assertions to make sure they trigger if
we go below 1. Formerly a negative refence count did not
trigger the assert as the refcount variable is u_int.
