Summary: signal handler in popen.c is totally broken

Initial Comment:
popen_timeout_alarm_handler() in popen.c is a signal
handler which does all kinds of stuff you better NOT
do in a signal handler. Plugins using this signal
handler should be rewritten to deal with a much simpler
signal handler, doing the bare minimum like setting a
flag.

For a better explanation of all the problems, please
