is to first write the deleted directory entry to disk, second write
the zero'ed inode to disk, and finally to release the freed blocks
and the inode back to the cylinder-group map. As this ordering
requires two disk writes to occur which are normally spaced about
30 seconds apart (except when memory is under duress), it takes
about a minute from the time that a file is deleted until its inode
and data blocks show up in the cylinder-group map for reallocation.
If a file has had only a brief lifetime (less than 30 seconds from
creation to deletion), neither its inode nor its directory entry
may have been written to disk. If its directory entry has not been
written to disk, then we need not wait for that directory block to
be written as the on-disk directory block does not reference the
inode. Similarly, if the allocated inode has never been written to
disk, we do not have to wait for it to be written back either as
its on-disk representation is still zero'ed out. Thus, in the case
of a short lived file, we can simply release the blocks and inode
to the cylinder-group map immediately. As the inode and its blocks
are released immediately, they are immediately available for other
uses. If they are not released for a minute, then other inodes and
blocks must be allocated for short lived files, cluttering up the
vnode and buffer caches. The previous code was a bit too aggressive
in trying to release the blocks and inode back to the cylinder-group
map resulting in their being made available when in fact the inode
on disk had not yet been zero'ed. This patch takes a more conservative
approach to doing the release which avoids doing the release prematurely.
ENABLE_SUID_SSH being defined reenable it for those that want it.
This follows discussion favoring the change from September. It
is not usually necessary to be setuid root, possibly less safe,
and less convenient (cannot use $HOSTALIASES, for example).

I opted to use Doug Ambrisko's WEP patches since David Cornejo's patches
did not include the necessary changes to ancontrol(8) to actually enable
and use WEP.
NOTE: I don't currently have access to an Aironet card, so I can't test
any of this. Everything compiles and close scrutiny doesn't reveal any
obvious problems, but Murphy's Law applies. This means I will probably
leave these changes in -current for a bit longer than usual until I'm
sure they work right.
linux_sigset_t by updating the linux_sigframe struct so as to include
linux's "extramask" field. This field contains the upper 32-bits of
the sigset. extramask sits behind a linux_fpstate struct, which I've
defined primarily for padding purposes.
While we're here, define LINUX_NSIG in terms of LINUX_NBPW (32) and
LINUX_NSIG_WORDS (2).
This fixes problems where threaded apps would accumulate a large
number of zombies. This was happening because the exit signal resides
in the upper 32-bits of the sigset and was never getting unmasked by
the manager thread after the first child exited.

done, so the correct directory is being checked. The mkstemp() call
is meant to create a temp file for stderrs when running filters. This
update also fixes log-file processing for remote (rm=) queues which
specify an input filter (if=). Before, filter-errs were thrown away.
Now they'll be copied to the queue's logfile (lf=).

This allows us to successfully attach early Storage Dimension cards.
Allocate mailboxes for the 742A bellow the 16MB limit. Although these
cards seem to be able to deal with all other types of data anywhere
in a 32bit address space, 24bit addresses are required for mailboxes.
