Thanks very much!  Were /usr and /usr/obj on different filesystems
and/or different disks?

1h45m is terrific compared to some of the others, but I can't say that
I have a stastically significant sample yet, by any means.

Added to my worldstone statistics:

I've written Colin to ask his opinion.  Can anyone else comment on the
ccache/world interaction problem?  This thread seems to indicate that
some issues have been resolved:

What branch were you tracking?  I try to note that in both the dmesg
and worldstone info.  In the meantime, I've added your dmesg to the
archive as u80_unknown_unknown.

Terrific, Steven -- thanks for testing this!
