systems) have actually implemented VMS/RSX - style ASTs in such a way
that they can be used as the basis for general-purpose  IPC. It's the best 
way to write some kinds of programs (e.g. real-time data acquisition).
They have a separate astpause function which waits for the process to
receive an ast or times out after some arbitrary time. I'm finding
that when combined with pipes or FIFOs you can devise very neat IPC
schemes.
