A purely theoretical follow up question (just because I am curious):
When you undef an object, is it really freed immideately, or just marked up for collecting, while the GC decides when to really take care of it all by itself? Reason I ask is that I seem to recall that you can not trust this to happen at any given point no matter what you do - but the odds are better if you undef.
Note that if you need that finegrained control over your memory and/or objects, if this really matters, then you probably have lots of other, more important problems, such as choice of language, hardware or the problem/project itself. :) So I am just asking technically, what really happens?
You have moved into a dark place.
It is pitch black. You are likely to be eaten by a grue.
