: I'm loading a FLT file into performer (1.2) and attaching it to a
: pfNode. After I have finished using it I pfRemove and then successfully
: pfDelete the object from the hierarchy (TRUE is returned). Although the
: object has been removed I'm not actually certain that the memory has
: been deallocated properly (gr_osview -a doesn't change). My question is
: simple :- Does it de-allocate all memory associated with the FLT file
: (Including all textures and materials) and if not is it possible ?

The memory allocator in IRIX (and all other environments I know of) does
not reduce the size of the dynamic allocation arena as memory is freed.
This is because it's expecting that you'll soon be allocating more data
and it should therefore keep it's cache of abandoned allocations ready
for service.

This implies that the memory allocated to your application represents
the high-water mark of dynamic allocation requests. This is not so bad,
though, as virtual memory operation means that any large unused memory
areas will be paged out if the physical RAM becomes needed later.
