Has anybody yet run into a situation where sendmail hangs forever in
thread_block()?  I'm wondering if recent VM changes might leave a
process blocked after certain kinds of page faults, or something like
that.  My wild guess is that this is happening to sendmail because it
tends to sit around for a long time, occasionally forking subprocesses
but not exec()ing.
