The memory is used in the buffer and page caches.

There is a trick: write a utility that allocates 350MB of memory and touches every 4k of it. That will force the kernel to shrink the caches. > (i'm tempted to get rid of blackbox and every app i use with it, but > then i will only use about 30MB of the memory) It wouldn't help you anyway.
