* That means that if this process exits it is closed and all the processes
* it contains are killed. All processes created with uv_spawn that are not
* spawned with the UV_PROCESS_DETACHED flag are assigned to this job.
*
* We're setting the JOB_OBJECT_LIMIT_SILENT_BREAKAWAY_OK flag so only the
* processes that we explicitly add are affected, and *their* subprocesses
* are not. This ensures that our child processes are not limited in their
* ability to use job control on Windows versions that don't deal with
* nested jobs (prior to Windows 8 / Server 2012). It also lets our child
* processes created detached processes without explicitly breaking away
* from job control (which uv_spawn doesn't, either).
