--TEST--
Test connection resiliency with a prepared statement and transaction.
--DESCRIPTION--
Prepare a statement, break the connection, and execute the statement. Then
test transactions by breaking the connection before beginning a transaction
and in the middle of the transaction. The latter case should fail.
