At this point I'm probably a week away from having something with the
obvious bugs all fixed, at which point I can start submitting it back
upstream.  The few patches I have to common infrastructure I'll just submit
to libc-alpha as git patches, then I'll probably just send a two-part patch
set to libc-ports, one with the linux/generic stuff, and one with the
tile-specific stuff.  (It looks like changes are never made as "git pull"
requests on the glibc lists, just as emailed unidiffs -- someone correct me
if I'm wrong.)

Linas, if you can wait a week I'd rather have you see the stuff I believe
to be working 100% to get maximum use out of you as a reviewer :-)  If you
need it sooner, of course, I'm happy to let you have something now.
