And backing out to the earlier patch removes the hangs, though statistical
insignificance and all that.
Ah, in answer to your earlier question, if you want it in v5.3, you
will need to take it (but I do humbly request that you wait until it
actually works). If you don't take it, I won't be submitting it earlier
than v5.4. Either way, your choice!
Thanx, Paul
