OK, thanks.

I also built the snapshot successfully on a Fedora 17 system that I
use for real work.  I just ran a performance test, FWIW.  I searched
recursively in our source hierarchy of 6044 regular files and 1102
directories for a simple string.

    time grep -Rin mystring src > /dev/null

Here are the results, averaged over three trials each, not including
any slow times clearly due to updating caches.

            2.12    2.21    2.21.78-7da30
            -----   -----   -----
    real    18.0s   1.08s   2.36s
    user    17.8s   0.96s   2.24s
    sys     0.12s   0.11s   0.10s

Version 2.12 was /bin/grep.  The other two versions I built myself.
