I've _never_ heard of it freeing something when it shouldn't. The main problem 
with false positives is that because it's conservative, on 32-bit systems, it 
will sometimes think that a block of memory contains a pointer when it doesn't 
(and therefore won't free the memory that it incorrectly thinks is being 
pointed to). But 64-bit fixes that. Regardless, a new GC is in the works, so 
the situation is going to improve.
