Possibly, but I have not had any further problems once it started working
again.  I have it configured as I want it, so I won't worry about it until it
happens again.  I have noticed sendmail blocking as I send a message through
mutt.  I presume this is caused by dns lookups, but it is nearly always brief.

strace still blocks if I just say:
$ strace cat file

It blocks, but will jump start if I 'ctrl+z' and 'fg'.
ioctl(3, PIOCWAIT
