This seems similar to the problems people have experience with
boost::this_thread::sleep (which I cannot reproduce), which relies on
condition_variable::timed_wait.

I don't think anything significant has changed in that area, so it
surprises me that you are experiencing problems only after upgrading.

Can you give more information about the problem? A small sample
application that demonstrates it would be nice.
