signals to running processes

[Rahul Dhesi]

I have lost track of whether the original poster, who wanted to be able
to send a signal to a process not owned by him, wanted to do it under
under BSD or System V.  If it was BSD, a possibility is to open an
Internet domain socket and set up a SIGIO handler.  When somebody--
anybody--tries to write to the socket a SIGIO signal will be seen by
the process.
