potential patch
After some debugging, I found that the open() of the control channel was
failing with EBUSY. So, I put the open in a loop to retry (for up to 10
seconds) if we get an EBUSY.
Note that I don't know why the module is busy then. Also note that this patch
doesn't fix the actual test case failures.
However, this patch does keep the module from being left behind.
