You wouldn't have a problem with SilkJS. Something like this works:
(function() {
var handle = null;
...
function connect() {
if (!handle) {
handle = mysql.connect();
}
}
...
exports.connect = connect;
}());
Every child would get a null handle at fork() time. So each child would call
your connect() method and get a new handle.
That's kinda rough, but I think you get the idea.
The handle variable could be a global variable, too, since those get cloned by
fork().
