# Some simple warm-body tests with a single database file in rollback 
# mode:
#
#   multiplex-2.1.*: Test simple writing to a multiplex file.
#
#   multiplex-2.2.*: More writing.
#
#   multiplex-2.3.*: Open and close a second db.
#
#   multiplex-2.4.*: Try to shutdown the multiplex system before closing the db
#                file. Check that this fails and the multiplex system still works
#                afterwards. Then close the database and successfully shut
#                down the multiplex system.
#
#   multiplex-2.5.*: More reading/writing.
#
#   multiplex-2.6.*: More reading/writing with varying small chunk sizes, as
#                well as varying journal mode.
#
#   multiplex-2.7.*: Disable/enable tests.
