There is a portability issue in signal handling code.

Some systems require to reset signal handler each time a signal was
received, while for others the handler is executed recursively destroying
CPU stack of running stunnel process.  It looks like I need to read
"Signals" chapter of the classic "Advanced Programming in the UNIX
Environment" once again and than review the code.  8-)

BTW: I'm rewriting libwrap code for stunnel 4.21.
