Description of problem:
On Xen, with two domains running (dom0 is FC3 and dom1 is Specifix Linux 0.20),
I keep getting (a) random segfaults occassionally, and (b) random error 139s
from python code that is forking-and-execing processes. Every time, if I repeat
the action that precipitated the segfault or error 139, it works the second time
around.

Version-Release number of selected component (if applicable):
xen-2-20050207

How reproducible:
Not reproducable
