I remember it well :-))
Here, the furniture's been replicated, but the house has been moved to a new address. The process ID has been changed (making a browser connection think we're done) and all the kids are sent SIGHUP, which says "We've moved on, and we're not saying where!"
If we have some reinitialization to do, we can do it in an _init() function and set the HUP handler to call it, or else just call it directly,
{
my $cpid = fork;
exit 1 if not defined $cpid;
exit 0 if $cpid;
_init();
}
I would also like to know what OP needs to do.
