#6288: popen deadlocks Paladin on multicore machines

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:
