Sounds about right.  I didn't get a match on the one string
I tested.  Takes anywhere from 11 to 13 minutes to grep through
*one* of the 8 files.  I scrounged around for speed enhancement
techniques, and that's about the best I could get it to do.

$ LANG=C grep -m 1 -F <hash> <file>

Anyway, I may try hashing with a newline.
