Memory allocated with the GC (e.g. using new) will never be freed 
if a reference is kept to it. Are you accidentally or 
deliberately keeping a complete history of all programs? Are you 
allocating any memory from anywhere other than the GC?

What OS? How much RAM? Are you compiling with -m32 (and 
conversely what happens if you compile with -m64)?
