--- Comment #16 from Mischa Baars <mjbaars1977 at gmail dot com> ---
And this all happened right after a found another bug (except from the
buffered output) in the kernel code. Full duplex transmissions display a
very serious slowdown on occasion (sometimes the very first time, sometimes
the 500th), but my thought being, who would want to destroy my computer for
stumbling upon someone else's programming mistakes? So I'm a little
preoccupied and out of the comfort zone, but I'll think about it.

Never actually used pthreads before. I used only fork() until recently
because of its simplicity and because it appeared to work sufficiently well
with PostgreSQL.

Clone() has the advance that you can pass arguments, i.e. the number of the
computation, so that in combination with an indexed output, you can now do
computations in parallel, solutions to differential equations at multiple
points in time for example.
