Removing XInitThreads from Totem
Bastien, you're not alone. If the JDS team complained to even Sun's X11 team about bugs after they applied that Totem patch, we'd tell them they're on their own and we'd never support an application that called X from multiple threads without calling XInitThreads first.
The Solaris Xlib is thread safe (though probably with a few bugs in corner cases still) based on the same X11R6 multi-thread code as everyone else, though we're currently working to reconcile the fixes from our fork with the current X.Org code as part of our ongoing project to un-fork Solaris X11 and bring it back to the X.Org code base. We're also looking at XCB in the future for a cleaner thread-safety model as well.
Update: As noted by trisk in the comments, this seems to have been caused by known Solaris libXi bug 6551484 - the engineer who had removed XInitThreads() from totem tried the test binary produced by the engineer working on the libXi bug and found it solved the hang problem she was seeing.

CR 6551484 probably refers to the same problem.
