38/*
39Martin,
40tis is a very simple test that I used to verify functionality and timing
41with 1.2.1 on NT and I can see how memory consumption grows linearly with
42time. When I ran my implementation I could see the program footprint of
43about 400K during the whole simulation.
44The test runs about 20 seconds and memory footprint grows to about 90MB. If
45you run it longer it starts swapping memory do the disk and goes very
46slowly. So I waited till it grew to 1GB and then killed it because all
47computer does at that point is swapping memory. I guess if you let it run
48long enough it would eventually die. I think this happens only with
49optimized libraries.
