I've seen this behavior many times. However, I am firmly of the belief
that this misbehavior is outside the realm of OpenLayers: the Google
Layer simply calls 'setCenter' many many times, most likely in a way
that is not designed to be supported by Google. 

OpenLayers has an internal 'moveTo' operation on layers that is called
differently when dragging. I expect that Google has a similar function
-- which explains why you don't see the problem on Google Maps
applications -- but without the code being available it's not possible
to check it out. 

At some point, I may try to form a small example that doesn't involve
OpenLayers which reproduces this, so I can take it to Google/Google
mailing lists, but it is my expectation at the moment that this problem
is not something that OpenLayers has control over.
