 There are some scenarios where child processes of the boss are not cleaned
 up well, notable cases are sending a SIGHUP and uncaught exceptions in the
 boss code.

 In either case, we should always close all child processes if the boss
 exits, so if it isn't available yet, we need exception-free process
 cleanup code (and point the correct handlers to it).

 For SIGHUP, this has been more-or-less addressed in #642, but at the time
 it turned out to be more work than we had time for. The changes made there
 are probably not applicable anymore, but have been kept around for
 reference in branches/trac642-historic.
