Comment:

 I've replaced all thread_yield with a new yield(unsigned) call that is
 based on Boost.SmartPointer's "yield_k" functions. This function
 increasingly tries to use heavier wait functions. First mm_pause, then
 SwitchToThread/Sleep(0) and finally Sleep(1).

 Iteration thresholds are taken from Boost.SmartPointer code, and those
 might not be optimal for all CPU types, number of concurrent threads, etc.
 I'll fix the bug with the commit, but reopen it if this doesn't solve the
 issue.
