Background: currently you can’t force a garbage collection [even if  
you’re pretty sure an object isn’t referenced] except by doing a  
GC.start, which itself isn’t guaranteed to collect anything, because of  
the conservative GC.

Rationale: If you could force collection [obviously it’s dangerous, but  
in certain controlled situations] you could avoid having to fire the GC  
as much, thus saving running time.

Thoughts?  
Thanks.

It is too dangerous, I think. Sometimes a small programming flaw  
is considered as a “security risk” these days.
