 Call the callback when $signal is received (the signal can be specified by
 number or by name, just as with C<kill> or C<%SIG>).
 
+Only one event loop can grab a given signal - attempting to grab the same

 EV will grab the signal for the process (the kernel only allows one
 component to receive a signal at a time) when you start a signal watcher,
 and removes it again when you stop it. Perl does the same when you
