What is the context? It's unclear to me if you're talking about PyPy
the Python interpreter, another stand-alone RPython program, or a
CPython extension module translated from RPython.
In all cases but the latter you should definitely try our own GCs
instead of Boehm. The generational GC in particular, while not
real-time in any sense of the word, is probably the one with the least
amount of long pauses - most collections are very quick.
