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