Steps to reproduce:
Appears to be completely random, although I suspect it occurs when system is
under heavy load (either disk or CPU.)

Never mind. I found out what the problem was.
Please see:


Setting kernel.randomize_va_space=0 in /etc/sysctl.conf
(echo 0 > /proc/sys/kernel/randomize_va_space) solved the problem.

It does seem to be a really bad bug introduced into the kernel,
but at least it's fixable for now.

Looks like this one can be closed?  It doesn't seem valid anymore.
