RE: [QSF] Re: POE+Signals : The final solution

Furthur notes :

1- The signal pipe needs to be rebuilt when you fork off a new process that
uses the same kernel.  Example would be a pre-forking server.  To do this, you
need to call $poe_kernel->has_forked.

2- Signals need to be masked while the signal pipe is being rebuilt.  We use
sigprocmask() for this.  This has been tested on cygwin, Mac OS X, Linux and
FreeBSD.  We don't now how compatible sigprocmask() is with more obscure
platforms.
