Acquires in exclusive mode, ignoring interrupts. Implemented
by invoking at least once {@link #tryAcquire},
returning on success. Otherwise the thread is queued, possibly
repeatedly blocking and unblocking, invoking {@link
#tryAcquire} until success. This method can be used
to implement method {@link Lock#lock}.
@param arg the acquire argument. This value is conveyed to
{@link #tryAcquire} but is otherwise uninterpreted and
can represent anything you like.
