Stevens APUE (s. 10.8) says:
"What happens if a blocked signal is generated more than once before
the process unblocks the signal? POSIX.1 allows the system to deliver
the signal once or more than once. If the system delivers the signal
more than once, we say the signals are queued. Most Unix systems,
however, do not queue signals. Instead the Unix kernel just delivers the
signal once."
