Comment(by greenfeld):

 With just runin-gtk and runin-memory running along with runin-sus, we
 still hang restarting the tasks, but possibly less often.   Two of three
 systems tested this way hung in runin over 24 hours, but one took 10 hours
 to hang.

 Just running runin-memory (X still active, runin-gtk not) did not hang one
 XO when tested with runin-sus aggressively running.

 We are now testing modified runin variants running 12.1.0 using the 11.3.1
 XO-1.5 kernel and vice versa.  This requires some changes to userland to
 get runin started since the /ofw directory doesn't mount promfs in 12.1.0,
 and /proc/device-tree only existed for XO-1.75 in 11.3.1.  Runin-sus from
 each version was copied to the opposite version of runin to get that
 going.
