Ok, good.  It was a desperate hack anyway.

Could you outline how you reproduced it?

One possibility I'm thinking is that each display-X (for example) has its
OWN lock, so if visual A is doing some X call and visual B is sync'ing ...
Or does it not matter if they're separate connections ?  
(provided that Xlib is threadsafe, I don't know if Debian's is)

Should go even faster with the -nodb option and xlib target :-)
