1. Conform to IEEE Std 1003.1-2004, which state that "Constructed
arguments cannot grow larger than 255 bytes", and
2. Avoid a buffer overflow.
Unfortunately the standard doesn't indicate how xargs is supposed to
handle arguments which (with the appropriate substitutions) would grow
larger than 255 bytes; this solution handles those by making as many
substitutions as possible without overflowing the buffer.
OpenBSD's xargs resolves this in a different direction, by making
all the substitutions and then silently truncating the resulting string.
Since this change may break existing scripts which rely upon the buffer
overflow (255 bytes isn't really all that long...) it will not be MFCed.
failure in the NFS server would result in a leaked instance of the NFS
server subsystem lock. Liberally sprinkle assertions in all target
labels for error unwinding to assert the desired locking state.

errors are in rarely executed paths.
1. Each time the retry_alloc path is taken, the PG_BUSY must be set again.
Otherwise vm_page_remove() panics.
2. There is no need to set PG_BUSY on the newly allocated page before
freeing it. The page already has PG_BUSY set by vm_page_alloc().
Setting it again could cause an assertion failure.

probably means it also requires a .so version
bump. Defer it until I finish some related
work on cleaning up error returns throughout
the library.

vm_page_io_finish(). The motivation being to transition synchronization of
the vm_page's busy field from the global page queues lock to the per-object
lock.

quietly, it now emits annoying but complete messages at best and
incomprehensible prefixes on average. During all of October, this is

People have a tendency to add things to libmap.conf and forget about them
(as we've seen in the mailing lists before).
The compat4x port should be used instead.
