+=head3 Restart Behaviour
+
+While restart behaviour is up to the event loop implementation, most will
+not restart syscalls (that includes L<Async::Interrupt> and AnyEvent's
+pure perl implementation).
+
+=head3 Safe/Unsafe Signals
+
+Perl signals can be either "safe" (synchronous to opcode handling) or
+"unsafe" (asynchronous) - the former might get delayed indefinitely, the
+latter might corrupt your memory.
+
+AnyEvent signal handlers are, in addition, synchronous to the event loop,
+i.e. they will not interrupt your running perl program but will only be
+called as part of the normal event handling (just like timer, I/O etc.
+callbacks, too).
