# TEST	rep102
# TEST	Test of exclusive access to databases and HA.
# TEST	Master creates a database, writes some txns, and closes the db.
# TEST	Client opens the database (in child process).
# TEST	Master opens database exclusively.
# TEST	Client tries to read database and gets HANDLE_DEAD.  Closes db.
# TEST	Client tries to reopen database and is blocked.
