Apparently the Windows version of IDL is being compiled with
a special compiler (whose name completely escapes me at the
moment) that has the ability to give freed memory back to
the operating system. As many people have pointed out, this
is NOT a normal feature of most standard operating system
libraries that use Malloc and Free to allocate and free
memory.

Yet another reason why I buy more Microsoft stock every
time the market dips. :-)

Cheers,

David
