Huh? It seems like the deterministic behavior of reference counting
would be of benefit to large, long-running programs. Or are you thinking
of large, long-running programs that create a lot of cyclic references?

Cyclic memory collection is a build option and, if enabled at build
time, it can still be disabled using the gc module.
