Subject: Begin collecting some of the statistics for block placement discussed
 on the mailing list. Suggestions for other statistics to collect would be
 awesome. =]

Currently these are implemented as a separate pass guarded by a separate
flag. I'm not thrilled by that, but I wanted to be able to collect the
statistics for the old code placement as well as the new in order to
have a point of comparison. I'm planning on folding them into the single
pass if / when there is only one pass of interest.
