[phobos] [D-runtime] Possible critical deadlock issue for 2.049

[Sean Kelly]

At this point, I'm wondering if there was some change in codegen that is causing an implicit allocation that didn't occur before.  It's a long shot though, since the code in question is mostly pointer assignments and the like (maybe a foreach loop or two).  I've had a delay getting the VM up (updating made it so the HD wouldn't mount on reboot), but once I do I'm going to look at the asm output of thread_entryPoint and a few other critical areas.
