From 4847e62e9fd1cd473cc180220a379efba93f94a6 Mon Sep 17 00:00:00 2001 From: John Hurliman Date: Mon, 26 Oct 2009 16:33:04 -0700 Subject: * Switched all operations on the list of clients that could be either sync or async to use Scene.ForEachClient() instead of referencing ClientManager directly * Added a new [Startup] config option called use_async_when_possible to signal how to run operations that could be either sync or async * Changed Scene.ForEachClient to respect use_async_when_possible * Fixing a potential deadlock in Parallel.ForEach by locking on a temporary object instead of the enumerator (which may be shared across multiple invocations on ForEach).
