probably depends on the thread library implementation. sigwait in
linuxthreads is just a complete hack.
i never tried rtsignals, but the first implementation of JACK tried to
use signals for IPC, and i found it 3-5 times slower than using pipes.
anyway, they are inherently slower than a pipe,
because the pipe model
doesn't require creation and use of a signal handling stack for the
task. the task is already blocked, and you just wake it up. with any
signal (including an rtsignal) you have to setup the signal call
stack first.
Also when using sigwait()?
