Would it be possible (or trivial?) to write a small C program to test
for memory overcommit behaviour? Might be useful to put in contrib, and
mention it in the Admin docs. There are just too many Linux variants and
settings to be sure of what exactly the memory overcommit policy is for
a particular kernel and distribution.

Linux 2.6 will apparently behave better. I guess they have learnt the
lesson. :)
