(Perhaps it depends on the protocol used for the IO but) eventually
client requests would be noticably lost/dropped and that's how the
server propagates the requested control onto the clients without relying
on the clients throttling themselves.

(Maybe better place to implement this would be a "testing" device mapper
target akin to the 'delay' one.)
