> 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.
