If a query on a partitioned table is in flight, and alter
table...exchange partition is issued against it, which, if any, of the
following is (are) true?
* Partition exchange waits for query completion, since it requires
a DDL lock
* Partition exchange occurs immediately, query uses blocks
formerly in the exchanged partition but now in the table that was
exchanged
* Query fails when it reaches the partition, throwing "no longer
exists" error
* Something else altogether
