# TEST  	rep028
# TEST	Replication and non-rep env handles. (Also see rep006.)
# TEST
# TEST	Open second non-rep env on client, and create a db
# TEST	through this handle.  Open the db on master and put
# TEST	some data.  Check whether the non-rep handle keeps
# TEST	working.  Also check if opening the client database
# TEST	in the non-rep env writes log records.
