Are all these process burning CPU? Esp. the first in each "pair" should
be doing next to nothing but sleeping, probably blocked in a select or
something like that, waiting for the second process to finish.

And the second process should also be mostly sleeping/blocked in things
like connect/select/read/write calls.

I'd try using "strace" to see what your processes are doing instead, or
why they keep waking up.
