Signals

[Pete Keleher]

I'm trying to write a simple implementation of an Unix shell to be used as a 
lab in a class, but I'm having problems handling ^Z. 

I install a handler for SIGTSTP via 'signal' and then send SIGSTOP to the
proper child via 'kill'. 'ps' says at this point the child is stopped and
soon swaps out. The parent is marked as sleeping. A 'printf' call followed
by a fflusch call immediately follows the 'kill', but it never happens.

Clues? Comments?
