- Any device driver that has a STREAM head sitting atop of it can
- send signal to a process willing to take it.
- Sockets are perfectly willing to send signals.
- Better non-STREAMS drivers of pre-STREAMS era were notifying
- processes with signals.
- In the context of the original posting, signals are used for asynchronous
- event notification, rather then IPC .
