There is a one deep stack for signals.  I think that Chris meant to say that
multiple instances of the same signal will all get coalesced into one as
long as the signal has not yet been delivered.

Think of Unix as a virtual processor, system calls are instructions, and
signals are interrupts.  In a processor, noone stacks interrupts.  The
only promise is that one of N will get delivered, N - 1 are all lost.
