Managed to reproduce without tapping any keys. Switched using mouse to xterm, and snatched this snippit from the terminal. Indeed, no keyup event is showing up until after I hit the next key sequence (a ^C) to terminate the stream of "s"es :

Since I believe the kernel is responsible for generating /dev/input/event* output, I would say that this is a kernel and not an xorg bug. Since there are no key repeat events being generated here the kernel must be getting enough information from the hardware to know that the key is not down, but is still not passing on the key up event.

Produced on Gutsy, linux-image-2.6.22-14-generic, Ubuntu package version 2.6.22-14.52. Just for good measure, xserver-xorg was 1:7.2-5ubuntu13.
