I am faced with the following problem and I would appreciate anyone
sending me a note of hope saying that I really do not have a problem.
Well, here it is :

 While in the main process, I SPAWN/NOWAIT a process that does something
completely different from what I am doing in the main process. The problem
arizes when the SPAWNed subprocess wants an interactive input (and it must
be interactive). Can the subprocess `hang' the main process until it receives
what it wants ? If not, what would you suggest ?
