is one, detect mbuf loops and stop, add an extra arg so you can only print
the first x bytes of the data per mbuf (print all if arg is -1), print
flags using %b (bitmask)...
No code in the tree appears to use m_print, and it's just a maner of adding
-1 as an additional arg to m_print to restore original behavior..

select(2), and discovered to my horror that ugen(4)'s bulk in/out support
is horribly lobotomized. Bulk transfers are done using the synchronous
API instead of the asynchronous one. This causes the following broken
behavior to occur:
- You open the bulk in/out ugen device and get a descriptor
- You create some other descriptor (socket, other device, etc...)
- You select on both the descriptors waiting until either one has
data ready to read
- Because of ugen's brokenness, you block in usb_bulk_transfer() inside
ugen_do_read() instead of blocking in select()
- The non-USB descriptor becomes ready for reading, but you remain blocked
on select()
- The USB descriptor becomes ready for reading
- Only now are you woken up so that you can ready data from either
descriptor.
The result is select() can only wake up when there's USB data pending. If
any other descriptor becomes ready, you lose: until the USB descriptor
becomes ready, you stay asleep.
The correct approach is to use async bulk transfers, so I changed
the read code to use the async bulk transfer API. I left the write
side alone for now since it's less of an issue.
Note that the uscanner driver has the same brokenness in it.

by default when named is enabled. Also, improve our default directory
layout by creating /var/named/etc/namedb/{master|slave} directories,
and use the former for the generated localhost* files.
Rather than using pax to copy device entries, mount devfs in the
chroot directory.
There may be some corner cases where things need to be adjusted,
but overall this structure has been well tested on a production
network, and should serve the needs of the vast majority of users.
UPDATING has instructions on how to do the conversion for those

standing ability to list a non-existant device in /etc/ttys to keep it
from dying. This is a documented feature of init(8):
The init utility can also be used to keep arbitrary daemons running,
automatically restarting them if they die. In this case, the first field
in the ttys(5) file must not reference the path to a configured device
node and will be passed to the daemon as the final argument on its com-
mand line. This is similar to the facility offered in the AT&T System V
UNIX /etc/inittab.
So rather than fix the man page to 'break' this feature, back out the change.
At the time this change was made, people felt that the spamage from
getty was annoying on headless consoles. Andrew Gallatin noted:

> Sep 26 11:00:11 monet getty[543]: open /dev/ttyv1: No such file or directory
and we went off and applied this hack rather than fixing getty to
sleep forever when it gets an unknown device, as was Andrew's other
suggestion. Since it breaks things, I'm off to do that instead.

1. Read data from good component for synchronization.
2. Write data to the same area.
3. Write synchronization data, which are now stale.

for the new thread. The rest of the fields in the pcb wind up being
written to before they're read as a normal part of the pcb usage but
this field may be read upon return to userland, having it be uninitialized
garbage is bad.
