Hello *,

I was reading through the docs of boost::thread lib and I can't find any
guarantees that when using upgrade_lock the writer (upgrader) starvation is
prevented. Are there any ordering guarantees, that if some thread is going
to upgrade the lock the threads which acquire the shared lock after the
upgrade request will not be able to acquire the lock until the upgrade
request was accomplished and released the lock?

Many thanks for help,
Ovanes
