I do have a second machine to do remote debugging, although running gdb 
on an Xserver is not all that easy. (mine refuses to start up when 
invoked through gdb, but attaching works fine. at least most of the 
time. valgrind is usable, too.)

But in this case, the mesa code runs on the client side, with dri mostly 
untouched, so there are no external locks taken. I manually looked 
through the xserver code. Kristians patches to the xserver gave a good 
hint where to look for the visual information sending code.

That is for someone else to answer.
