This assumes that you will always receive USR1 before every STOP, but
since STOP is uncatchable like KILL, this may not always happen. Imagine
an external process sendind it without sending USR1 first, and suddenly your
assumption is no longer true.

Granted, edge cases like this are rare, but they do happen. Signals
are things that should be given a bit more consideration than usual when
dealing with things like handlers.
