FASTBuild uses the system temp dir. This can be overridden by setting the FASTBUILD_TEMP_PATH. This can be useful in certain cases, such as when certain Anti-Virus software is used that prevents executables being spawned from the temp directory.
FBuildWorkers signal their availability by writing a token to the "Brokerage Path". The location of the brokerage path can be set via the FASTBUILD_BROKERAGE_PATH.
