It's not really endless use of memory and it does free. Depending 
on the strategy then it does so at different times, such as when 
allocating, but not enough memory has been allocated already.

The problem with GC is that the lifetime sometimes exceed what's 
expected.

Personally I don't have a problem with the GC.
