I would prefer that as well.

FWIW, the core Mesa code I wrote for GL_AMD_performance_monitor may be
pretty poor for Radeon - it uses bitsets for a lot of things, which made
sense on i965 since I had < 64 counters to expose.

The last time I looked at the closed source AMD driver, it exposed over
6,000 counters.  So you may need some better data structures...
