dri-per-screen-lock-refcount-1.patch

in fact it does matter.  the scenario is:

server takes lock on screen 1
server goes to lock screen 2, sees global refcount > 0, skips
server touches screen 2 while DRI client active on screen 2

in other words, DRI activity on screen 2 -> death.  attached patch moves the
refcount into the DRIScreenPrivRec, so the lock will get taken for every
screen.
