[Bug 29020] [r300g] Wine d3d9 tests hardlock

https://bugs.freedesktop.org/show_bug.cgi?id=29020

--- Comment #6 from Marek Olšák maraeo@gmail.com 2010-07-12 19:17:04 PDT --- Multiple simultaneously running contexts are most probably the cause of these hardlocks, because this way the driver may generate pretty much a random command stream which has valid register writes, meaning that the CS checker doesn't notice anything, and the hardware goes crazy.

Wine uses multiple contexts quite often, if not all the time.

Soon I am going to rewrite winsys for it to support multiple command streams, and then we'll see if it resolves this issue...
