On a uni-processor the process table is effectively locked because
no other process can run while the kill() system call is running.
System calls only relinquish the CPU when they want to.  kill() is
not one of them.

If it's a uni-processor and they have the same process group its easy.
A multi-processor or something calling setpgrp() is another problem.
Your process spawning may vary.
