In 5c8340d2 we said:

    dbclose now uses defer almost everywhere - there are still few places in
    tests, where one test function is opening/closing test database multiple
    times - those were not (yet ?) converted.

Let's convert those remaining places now, because when wendelin.core
tests are run wrt plain ZODB4 (contrary to ZODB4-wc2), many tests fail
at fileh_open time, e.g.

        @func
        def test_bigfile_filezodb_fileh_gc():
            root1= dbopen()
            conn1= root1._p_jar
            db   = conn1.db()
            defer(db.close)
            root1['zfile4'] = f1 = ZBigFile(blksize)
            transaction.commit()

    >       fh1  = f1.fileh_open()
