LOL. Likely so, but I'd prefer not to have to muck with my system 
settings just to be able to deal with the dmd build. What would 
probably be better would be to fix it so that the update program 
can continue from where it was left off if it needs to...

Regardless, this situation caught me by surprise, and it was a 
result of dmd's loss in performance with the switch to D.
