>Description:
This machine is running a sendmail with profiling compiled in.  In
tracking down a weird kernel performance bug, I compiled a profiled
kernel and tried running it.  Whenever I start sendmail under this
kernel, though, the machine entirely locks up; pcvt won't even change
to other virtual terminals.  This behavior occurs when sendmail is
started as root from /etc/rc, and it also occurs when my mailer tries
to run sendmail as a non-privileged user.
