[Mesa-dev] [PATCH 0/5] use atomics for reference counting

[Timothy Arceri]

Hi,

I've been looking into this recently also. Unfortunately I don't think 
these will get applied as is.

These changes have been submitted before but rejected because they make 
existing race conditions worse. We really need to fix those first, I 
really think we are going to need some multi-threaded piglit tests to 
test some of this.

Also I think some of the locking (e.g. arrayobj, pipelineobj) can be 
dropped if we drop support for the GLX_MESA_multithread_makecurrent 
extension (which I believe we are planning to drop).
