I'm not sure what "flushed" means in this context.
(I *have* heard the word "flushed" used in the Windows 95
context, but I don't think that is what you mean here.)
IDL does clean up memory at the end of each procedure.
Memory doesn't get returned to the operating system,
typically, but it does get reused internally. But, as
you well know, with an unsupported operating system,
all bets are off. :-)
Cheers,
David

Dear Andrew,
are you using pointers. If so do a ptr_free.
