	// Set bestNonPreferredAffinityCount to help decide which affinity mask is
	// preferred amongst all non-preferred hints. We calculate this value as
	// the maximum of the minimum affinity counts supplied for any given hint
	// provider. In other words, prefer a hint that has an affinity mask that
	// includes all of the NUMA nodes from the provider that requires the most

	// read.

	// These steps are complicated by the rules around foreground process
	// groups. A process group cannot be foreground if it is "orphaned",
	// unless it masks SIGTTOU.  i.e., to be foreground the process group
	// must have a parent process group in the same session or mask SIGTTOU
	// (which we do). An orphaned process group cannot receive
	// terminal-generated SIGTSTP at all.
	//
	// Achieving this requires three processes total:
