It hangs on customer machines not mine where I cannot examine it
too closely (no gdb, etc). It monitors the file system, running
kqueue on up to 2000 disk inodes. It has a unix domain socket
to another process. When I look at with ps -x the status is Us.
If I kill the companion process, one of the threads will abort
the entire process on a broken pipe; then the status is Es and
it's still hung.

This can persist for days, until someone notices it. The only
recovery I know of is a reboot. I do know kqueue panicked 10.3.
I wonder if it's still broken or 10.4.9 broke it.
