They still probably won't in the immediate (as I'm mostly working on Power matters at the moment) but since there seems to be some interest, hopefully I'll be doing them in a month or two.  Once these problems are fixed, it's likely that, experiments confirming, there won't be any more reason to keep 4BSD around.  One of my personal goals is to deprecate 4BSD in 16 if possible, as it is more and more irrelevant on modern machines and seems too lightly tested.

Please, do not deprecate 4BSD.  Although it's been
a long time since I benchmarked 4BSD vs ULE with my
OpenMPI-based code, 4BSD handled the work load much
better than ULE.  Yes, I made Jeff aware of the
situation.

It's unclear how you conclude that 4BSD is lightly
tested.  Maybe 4BSD simply works and there's nothing
to report.
