o Miscellaneous bugfixes.  As I've said in calls, anything making use of
threads will die very quickly with xc/lib/X11, but works fine with
/cvs/xlibs/X11.

However, I think this is a 1.1 thing (i.e. not for now).

Right -- it seems to be very cleanly abstracted, and should be easy to
tack on to the monolithic tree.

Absolutely, and I will be pushing it with some packages.  I want to see
XCB tested.

I don't think we do.  Sergey, can you please comment on the state of
your work relative to /cvs/xorg/xc HEAD?
