The filename is /home/shannon/.history.datsun, which is what I have
HISTFILE set to.  Again, it's doing setattr, which it shouldn't be doing
for $MAIL.  And, based on the dtrace output, the setattrs aren't at
any obvious period.  Even stranger, despite the fact that I have something
like eight shells running, the calls are coming from a shell from which I
started another (superuser) shell, from which I'm running the dtrace
command.

What is "set #"?
