According to pthreads docs: "Mutexes can be applied only to threads in a

Maybe semaphores are right solution ?
Could this help? It is global to processes, and not just threads.
Not sure how you would use it though. I'm not the expert on linux
internals. ;-)
------ man futex --------------
<snip>
A futex is identified by a piece of memory which can be shared between
different processes. In these different processes, it need not have
identical addresses. In its bare form, a futex has semaphore semantics;
it is a counter that can be incremented and decremented atomically;
processes can wait for the value to become positive.
