wait on ipc message

[pgd at bbt.se]

I want to stall a process, to wake up on a message received
through a SYSV ipc message, or data available on any file.
That is, i want a select/poll to also include messages received
through an ipc channel.

Is this possible, somehow?

No sockets, no streams, no multiple processes solutions.

What I want to do is to simulate sockets with ipc messages.
