Hmph. A user-process causing the operating-system to hang. It's a
solaris bug, and no mistake.

My last job, we invested heavily in Sun hardware. Sun hardware is good.
But we got very sick of the bugs in the solaris 2.5 IP drivers. Very
VERY sick. Ultimately we started replacing the OS with whatever we could
run on them (FreeBSD at the time), and mothballing the ultra's and
netra's until linux or BSD caught up with them.

Maybe 2.6 fixes this. I dunno, but I recall weary times going over
bug-lists that seemed longer than the feature list and wondering "why".
Nevertheless, the hardware is good. All it needs is a 'rocking' OS to
put on it.
