Hi Frank, Ken's QA farm probably does cover those testing combinations.
But until the issue itself is better understood and we are sure of the QA
coverage, it might be better if pmwebd used the PM_CTXFLAG_EXCLUSIVE flag
to pmNewContext(), when in live mode. That's a much less invasive change
(just to pmwebd). Thoughts?
