Run a background task while waiting for a future that should occur.
This is useful for running a task which you expect to produce side effects that
mean the task is operating correctly. i.e. reacting to a peer action by producing a
response on a client’s hanging get.
background_fut
is expected not to finish ans is returned to the caller, along with
the result of result_fut
. If background_fut
finishes, this function will panic.
