Quite a few notable places in the Python sources expect realloc(...) to
relinquish some memory if the requested size is smaller than the
currently allocated size. This is definitely not true on Darwin, and
possibly other platforms. I have tested this on OpenBSD and Linux, and

Your expectation is not correct for Darwin's memory allocation scheme.
It seems that Darwin creates allocations of immutable size. The only
way ANY part of an allocation will ever be used by ANYTHING else is if
free() is called with that allocation.
Ya, I understood that.
Encryption/decryption support. Will most likely require a C extension since
the algorithm relies on ints (or longs, don't remember) wrapping around when
the value becomes too large.
You may want to do this in C for speed, but C-style int wrapping is
easily done by doing something like x = x
