Additions

enableProcessJobs :: CreateProcess -> CreateProcess

Enable process jobs to ensure accurate determination of process completion in the presence of exec(3) on Windows.

Unfortunately the process job support is badly broken in process releases prior to 1.6.8, so we disable it in these versions, despite the fact that this means we may see sporatic build failures without jobs.
