Note that this test might be affected by the fact that bash will _not_
abort the "sleep 400"; it will wait until it has finished before
executing the trap function(!) From man bash:
If bash is waiting for a command to complete and receives a signal for
which a trap has been set, the trap will not be executed until the com‐
mand completes. When bash is waiting for an asynchronous command via
the wait builtin, the reception of a signal for which a trap has been
set will cause the wait builtin to return immediately with an exit sta‐
tus greater than 128, immediately after which the trap is executed.
Thus, if you do
sleep 400 &
wait
instead, the trap function will be called as soon as the signal
arrives. I got bit by this behaviour trying to do exactly the same that
you did. :)
