I am checking UnixOSProcessPlugin >> primitiveForwardSignalToSemaphore and it seems it needs to do quite some work in order to place a signal handler for things like SIGCHLD in order to get a Smalltalk semaphore signaled upon receiving SIGCHLD or whatever signal.

So...I wonder...is there something today (nowadays) in latest VM that would allow me to set such a handler without such kind of primitive?

Thanks in advance,
