Comment (by mascguy):

 Details for operation `reclaim`: The check for unused distfiles is the key
 area where I've noticed the most slowdown. And interestingly enough,
 immediately running a 2nd iteration - with a potential benefit from a
 primed filesystem cache - doesn't yield much of an improvement. So
 something is coming into play.
