Frank,

Just a quick update ... I have pmwebd working with -M 4 now ... but it
required a lobotomy for the read_cache used in interp.c ... given the risks
here and the complexity of the code, don't expect a commit "any time real
soon", but don't waste time trying to debug in parallel either.

Initial speedup is only 10% on a 2 CPU VM ... so that's not too encouraging
... but let's wait until I have the final fix done before we get too excited
or too depressed.
