When long running functions like cb_erase and cb_flash are executed in a
poller, we can't currently use another poller to check if it is time to
send a keep alive message.
If we add a slice to poller_struct that is checked and then acquired in
poller_call, it would be possible. But as I wrote, we might then want to
limit the number of pollers executed "in parallel" because of the
limited stack space.
Having a slice in poller_struct also allows pollers to list the
resources necessary to run them.
Best regards
Daniel
