This is a problem with the return value of signal handlers:
that last one overwrites whatever the previous handlers returned.
Note that this is a general problem, not related to the perl binding.
You should return TRUE if you handle the event and don't want
it to propagate, check the documentation and/or the mail archives.
It doesn't seem you need connect_after() here though, so you better
use a simple connect().
