I've been working on RealTimeX for a year and a half now.  If you have access
to last year's Xhibition '90 proceedings, there a paper "The Application of
Real-Time Paradigms to the X Window System" that describes what RealTimeX
contains.  There will also be a paper at Xhibition '91 (I haven't finalized
the title) that describes the current state of the project.

Briefly, RealTimeX supports prioritization of windows and clients, as well as
preemption, synchronization, and determinism support.
