bandwidth for other processes. Since the sleeping is done from
userland, this avoids the locking issues that affected the kernel
version.
The algorithm used here is to measure a moving average of the times
taken by a sample of read operations and then delay 1 in 8 reads
by 16 times the measured average. This should correspond to a factor
of 3 slowdown, but in practice the factor is larger (3.5 to 4) due
to hz rounding effects.

live filesystem. To obtain a consistent dump image, dump takes
a snapshot of the filesystem and then does a dump of the snapshot.
The snapshot is removed when the dump is complete.
Also add an operator warning that the `L' option should be used
if dump is run on a live filesystem without the `L' option being
specified. The alternative would be to silently use a snapshot
any time that a live filesystem is dumped, but this change in
dump semantics seemed too drastic at this time.

partitions to Vinum and was broken by recent more stringent overlap

would be to have the loader understand a subset of Vinum partitioning

Approved by: roberto
'-p' is used on the reboot(8) command line.
This is intended for use when you want to attempt a power down
action, but you want the system to reboot (not halt) if the
power down action fails.
This is typically useful when the power-off action performed by
the kernel consists in signalling an uninterrupted power supply
that it should shut down its inverter if mains power has not returned.
The behaviour of shutdown(8) and init(8) is not modified;
only the behaviour of invoking 'reboot -p' manually is
modified, and then only in the case when a power-down action
fails.

old as/ld/etc - I have not removed these yet, pending their move to ports.

in /etc/fstab. This isn't a real fix though and I'm still not sure
why it started failing. mount(8) breaks up the nfs args into seperate
repeated '-o option=value' arguments. But, the altflags variable that
we use to track things is incrementally built up each time we see the
next option and shows us the cumulative set of flags, not just the
flag that we are currently looking at. As a result, the strstr hack
for looking up flags in a giant -o opt=val,opt=val, etc string was failing
and causing a segfault. I do not know what changed recently that caused
this to suddenly break, but the code has been rather bogus for some time.
