 problem : GL application hangs at starting (quake3 and a threaded)
 when running a multithread application, any call to _XRead should
 be done after a XLockDisplay is called. If you don't do that,
 a call to _XRead may make a call to _XWaitForReadable that calls
 XUnlockDisplay then XLockDisplay then the application freezes in the
 next XLockDisplay
 this is not the case in :
 glxext.c:387 and glxcmd.c:1439
 the correction should be fairly easy, moving the XUnlockDisplay done
 earlier at the end of the function and anywhere in the path where
 the function exits
 I can provide a patch if wanted
 
  Please do.

 Michel, do you have a patch for this.  I think this problem has come up in
 a separate instance with multithreaded applications

Yep, here.

VTK, Q3A (SMP?), glthreads, manywin, etc.
Any change this could cure wincopy, too?

 -- it would be good to get it resolved.

Keith, I'm willing to test all what I get.
Starting with your latest comit.

 In general, this is one of those DRI CVS tree and XFree86 CVS tree have
 greatly diverged problems, which will hopefully be fixed soon when the
 two trees are resynced.  This resync is currently being planned and will
 hopefully happen sometime soon.

Hear ye!

That's exactly what I ask for in the RandR Support on XFree86 4.3 thread.

I think we need more often a resync.
Maybe in an extra branch? Some like xfree-cvs-sysnc-branch?

 Michel, thanks for the patch!  I will aplly these to the XFree86 tree.
 As we discussed in our private e-mails, when you have time to get to the
 other changes to the Radeon driver in the DRI tree, please send patches
 either to me or to the XFree86 patch list.

That's the problem with all the new subsystems (DRI, Gatos).

Regards,
Dieter
