The commit 3c1308ed890e adds a guard to stop signal handling on exit()
in call_signal_handler(). However, the signal that is already queued
but does not use signal handler may be going to process even with that
patch.
This patch add one more guard at the begining of sigpacket::process()
to avoid that situation.
