Ok, with /selinux/compat_net set to 1, I can go into enforcing mode
on my rhel5 beta 1 targeted system.  Its got selinux-policy-2.3.3-22.

The first time I tried the same thing on my fc6/mls system it killed
all my network sessions.  The second time I tried it my established
sessions stayed up but the mouse quit working.  This system has
selinux-policy-mls-2.3.16-6.
