yes, I think we may want to explicitly cancel this workq.. this
in rds_conn_destroy().

I'm trying to build/sanity-test (if lucky, reproduce the bug)
as I send this out.. let me get back to you..

If I have a patch against net-next, would you be willing/able to

sure how we can check that "the fix worked"..
