OK. You might find this useful:
ftp://ftp.uk.linux.org/pub/linux/sct/vm/mtest.c
which is a small utility I wrote while I was testing the
swap cache code. It creates a heap of memory, forks a variable
number of reader and/or writer processes to access that heap,
and touches/modifies the heap randomly from the children. It
is very good at testing the swap code for pages shared over
fork. It's what I use any time I need to push a box into swap
for VM testing.
