Disables the current thread for thread scheduling purposes unless the permit is available.

If the permit is available then it is consumed and the call returns immediately; otherwise the current thread becomes disabled for thread scheduling purposes and lies dormant until one of three things happens:

• Some other thread invokes LockSupport.Unpark(Java.Lang.Thread) with the current thread as the target; or
• Some other thread Java.Lang.Thread.Interrupt the current thread; or
• The call spuriously (that is, for no reason) returns.

This method does not report which of these caused the method to return. Callers should re-check the conditions which caused the thread to park in the first place. Callers may also determine, for example, the interrupt status of the thread upon return.
