This may not answer your question directly, but if you call
your program very often, I'd keep a daemon running, and the
program itself would merely contact the daemon to tell it
what to do. This way, there is no init time (just when loading
the daemon).
However, depending on what you do, it might be too much in
memory (to keep the daemon in-core at all times). As usual,
YMMV, each situation may need a different setup.
