wine users - May 2011 - Frequent Starcraft II crashes.

Recently I've been getting frequent Starcraft II crashes. They started out
very rare (every other day or so), then recently have been happening every few
minutes.
Here's the terminal output I get when I run Starcraft II and it crashes.

I'm pretty sure the last two lines are the root of my problem, but googling
the error didn't help me at all:


Code:

err:ntdll:RtlpWaitForCriticalSection section 0x1726c20 "?" wait timed
out in thread 0027, blocked by 002a, retrying (60 sec)
err:ntdll:RtlpWaitForCriticalSection section 0x1726c20 "?" wait timed
out in thread 0027, blocked by 002a, retrying (60 sec)



Can anyone help me out?[/code]

Forgot to post my system info.
Wine version is 1.3.17. Linux version is Sabayon 5.5. Kernel is 2.6.38.
Graphics card is an 8800GTS 512MB, CPU is a Q6600. 

I was running it with everything on either medium or high at 1920x1080, but even
with all the video settings on low it still crashes.
