readOnly()
call returns. This call can be called concurrently
(and indeed until the operation completes, all calls on the Set from any
thread either complete normally or end up calling readOnly()
internally).
This call is useful in debugging multi-threaded programs where the
Set is constructed in parallel, but construction completes after some
time; and after construction the Set is only read. Making the Set
read-only will cause updates arriving after construction is supposedly
complete to throw an IllegalStateException
.
