I had forgotten that there was a public API, ThreadGroup, that exposed some
of this functionality.  Sadly I think that we may have to keep this, for now, and 
remove it in 10.

ThreadGroup::allowThreadSuspension should, however, have its @Deprecated
annotation updated with ‘forRemoval = true’, then removed early in 10.

I can’t remember if this was on Stuarts list or not, but I think it is ok to do it
separately anyway.
