    In fact I tried to `strace -f -T` it and it seems that in the
first second or so it `stats` all the files that exist, and then it
just waits 14 seconds computing something (100% processor), and
concludes that all is already built. (This is after I've already
successfully built it once).

    But any further profiling I didn't do as I've stumbled upon this
issue just about an hour ago...
