During the xid_wraparound test in testmodules-install-check-C two
clusters are running at the same time. This fact could make the
xid_wraparound test slower by any chance.

+1 not running it twice.

There are test modules that have only TAP tests and are not marked as
NO_INSTALLCHECK, for example test_custom_rmgrs. Probably we don't want
to run these tests twice too?
