okay let's go with the above suggestion than ? and overall let's only
add to rc when there are multiple users to the function with prep
patches moving the code, otherwise it gets bloated for no reason..

overall speed of the testcase is also very important since this gets
run with bunch of other testcases/testsuite(s) so keeping the testcase speed
minimum is always desirable ...
