From 2ab455a8fa946cb8d599018c2f861f1fe909c545 Mon Sep 17 00:00:00 2001 From: Guido van Rossum Date: Wed, 28 Jul 1999 21:39:28 +0000 Subject: Another patch from Andy Dustman: """ Here's a patch for the ForkingMixIn which will prevent the server from forking itself into the ground. Note: I've tested a very similar patch (subclassed ForkingMixIn) but not actually tested this one. As you might surmise, this was done out of necessity... If the maximum number of children are already running, block while waiting for a child to exit.
