I've tried this.. unfortunately ( In windows NT anyway.. I haven't
tried else where ) It does not seem to actually release the memory as
such.

Internal to IDL, it may mark that region of memory as freed, but
Windows never receives that memory back until IDL is closed. It would
also appear that any additional memory allocated doesn't utilize this
memory which idl has already allocated, but instead pulls more off of
NT's heap.

It creates a pretty big problem for some programs I'm working on.

Maybe I'm doing something wrong.

Just thought I'd add my experience.
