 This only occurs when multithreaded builds are enabled. Here are the steps
 to reproduce the error:

 1) Load a project on an SMP machine.
 2) Force a rebuild of the project
 3) Run the build.

 On my quad core system, perhaps 1 file might get built. Typically not,
 though. It deadlocks. Killing Paladin from the Deskbar at this point
 causes a crash with the following backtrace:
