I know that you know this, but Ondrej is talking about cthreads in one
of his message, so I tried to politely set a trigger.

This is because Michael Van Canneyt pointed me to "man sem_overview".
The first Google search pointed me to
http://linux.die.net/man/7/sem_overview where I found the "Named
semaphores" with functions sem_open, sem_close etc. with the
description that they can be used across processes. A quick search in
FPC sources pointed me again to the cthreads unit.
I haven't done any Linux development with semaphores, so sorry if I am
completely wrong here. I will also welcome if you correct me.
BUT semaphores are not directly needed by the IPC. simpleipc doesn't use
them either.
It would be nice to have solved the issue with double file locks on
unix, but this is not the core problem.
