Question: First off, sorry for the cryptic question.

My team is currently using Selenium 2.0rc3 (with python) for testing our web app with chrome. When we used the 2.02b version of Selenium, our test passed (it was a little slow and we had small hacks that we added to webdriver). After we upgraded, the test became extremely fast and started failing. After debugging we found out most test failed because webdrivers click() function was not blocking() successive calls. Currently we added a sleep()/timeout of .5 secs after each click and while this solves the immediate problem, it doesn't quite achieve our main goal (which is to speed up our test)

Answer: 
I've tried the selenium-2 rc3 python bindings for chrome. My experience was the opposite of what you're describing - after clicking, the driver didn't know that the page was ready for it to continue. So instead of speeding up the tests, they turned out very slow (because the driver was waiting for ages). However, the firefox driver seems pretty stable - maybe you should stick with it until the chrome driver gets baked a bit more.
If the click() executes ajax calls I would suggest you to use NicelyResynchronizingAjaxController
