Pike doesn't use memory compaction either, and also places pretty much
everything on the heap. Yet its processes don't need to be restarted;
in fact, everything's designed around keeping stuff running
permanently. As Emile said, it's not a requirement, it's a
compensation technique. I've yet to build a Python process that runs
for an entire year (as I'm not confident that I can get it so right
that I don't need to update any code), so I can't say for sure that it
would work, but I do have Python processes running for multiple months
without suffering serious fragmentation.
