Yes, i think sometimes it happens that the signal interrupts us just
during ssl-stuff. I can reproduce that by specifying a short timeout of
one second (the "alarmfunc called" was added by me):

* Closing connection #0
curl: (35) SSL: error:00000000::lib(0) :func(0) :reason(0)

Yes, that could be a solution. I'll try to play around with this a little
