// FIXME - I've added a FIXME tag here because despite the changes made for portal2,
// I'm not at all happy about nuking some of these.  In particular removing mutices
// and the "WaitForSingleObject" functionality seems like a recipe for disaster in
// a multithreaded environment.  Bottom line, I wouldn't mind having a second set of
// eyes give this a once over.

// @wge Doing the same for OSX. Same concerns apply.
