I disabled async DMA for R700 due to stability issues and hangs. The core
problem hasn't been fixed and will show up once we enable async DMA again.

To answer your questions:
1) --enable-debug has a significant performance impact, because it disables
compiler optimizations (forces -O0).
2) Yes, restarting the X server is required. The environment variables only
affect the terminal where they are set, so they can be useful if you just want
to test one app without affecting your system and other apps.
