msztest.c -- Testcase to show how to keep the heap really huge

Should upload this too.  This shows an example, albeit a controlled example, of
a program allocating a huge heap, then holding it for the sake of 100 bytes of
memory.  If it were mmap() rather than current malloc(), it would free the 100M
back to the system.

Run top, then run this in a terminal next to it, and watch the state of its
memory usage at every point where it sleeps.
