This is absolutely great news Andy, thank you!!  I think I caught
elsewhere that you're also squashing the remaining issues where a
"changes" scan gives different results than a "wipe and rescan", so
this will rock..

That's a fine answer; I've been planning to go grovel around in there
for a few years now, so maybe after your stuff gets merged to 7.4
trunk I'll play around with it.  Thanks for the pointer to the
profiler - perl's not really a primary language for me so that should
save me some time.
