Description

According to the specification wait/join or sleep methods should check if thread was interrupted before entering wait. DRLVM hythread implmentation do checks interrupted status(see hythread condition implmentation), however thread may be interrupted just after the status was checked and before entering condition wait. Thus it's required to ensure that waiting state will be reached having interrupted status unchanged.
