Continue discussion of signals, fork, and all that from last time.

Depending on time, write and run some of the fork/exec/signal_handler code from the text : alarm.c, shellex.c, sigint1.c ; do practice 8.7 in class. (All this is from code.tar available from the textbook website.)

Note use of 'static' variable in alarm.c

signal1 through signal4 looks at queuing issues with signals.

race conditions: procmask1, procmask2

Are we having fun yet?
