Unless you are talking about a very long-running server program, like a service that listens on a socket or a data queue, and is essentially a "never ending" job, there is really no point to ever doing a DEALLOC. This just adds unnecessary overhead. The ILE heaps perform much faster if all you ever do is ALLOC, because internally it just advances the pointer into the free space, and does not have to worry about "holes".

So, for most jobs, it is far more efficient to just wait until end-of-job and let the system take care of "throwing away" the entire heap, rather than incurring all of the overhead to issue DEALLOCate each chunk of storage you ALLOCated.
