But think about it: a garbage collector can release memory *as soon as

In environments which provide general purpose pointer types which can be
assigned to addresses of explicitly allocated memory (like C and C++),
garbage collection becomes an NP-hard problem.  In environments which have
no end-user accessible pointer type, explicit memory allocation is
superfluous.

(...) This is FUD. What causes Java to gobble memory is more likely (a) the amount of header overhead it places on objects (more to do with hashing support than gc, I suspect) and (b), to a lesser extent, the fact that objects are never "expanded" (...) (25 years ago, 8-May-99, to lugnet.robotics)
