the execution of the tests

sets the "swsbounce" magic mode. If there follows a request for the SAME
test number and the SAME part number, this mode will make the server bump

Test case 153 uses this in case you need an example. It is pretty involved
and hard-to-use, but then the situation is pretty special over all. Enjoy.
