hostname rather than an IP. The code was copying the pointer to the
IP address instead of the IP address itself. The bug has existed
ever since ypset was first imported in 1994.

- Ensure that the buffer ends with "\n\0" to avoid special cases
and allow the use of strtol().
- Use strvisx() on each complete line instead of character by

lookup on an IP address from the packet (such as the IP that sent
a TTL exceeded error). If the DNS lookup takes a long time, ^C will
appear to be ineffective since the SIGINT handler just sets a flag
and returns. Work around this by exiting immediately on receipt of
a second SIGINT when DNS lookups are enabled.

the "disappearing subdisks" problem when new subdisks can't be created
due to some errors.
This is in fact an ugly hack, but a more elegant solution would probably
require a redesign of vinum in several places.

mindful of blocking on disk I/O and instead return EBUSY when such
blocking would occur.
Results from the DeBox project indicate that blocking on disk I/O
can slow the performance of a kqueue/poll based webserver. Using
a flag such as SF_NODISKIO and throwing connections that would block
to helper processes/threads helped increase performance.
Currently, only the Flash webserver uses this flag, although it could
probably be applied to thttpd with relative ease.

Renaming a file is effectively a way to modify it.
For instance, if a malicious party is unable to delete or overwrite

on the card, unmap it first. This allows it to be picked up properly when
the queue gets kicked again. This was the root problem for the lost command
(i.e. stuck in getblk/vinvalb) problem. While here, panic if commands don't
map correctly instead of just silently ignoring the problem and dropping
command. Also slow down the dynamic allocation of new commands.
It should be safe to go back into the aac waters. Thanks to everyone who
suffered through this and provided good feedback.
