Kenji, if creating and joining new Pthreads is overkill, there's another
"you must be joking" way: just increase the number of scheduler threads.
The "erl +A" flag is just waiting to be (ab)used this way. :-)
If you needed to avoid having too many of these running at one time, and
each one is going to run for 10s or 100s of milliseconds (or more), then
writing a simple gen_server to provide a rate-limiting/admission-control
mechanism would have relatively zero overhead.
