module Sequencer: sig .. end
A sequencer is a throttle that is:
- specialized to only allow one job at a time and to not continue on error, and
- generalized to carry its own state, and enforce mutually exclusive access to that
state by the jobs

val enqueue : 'a t -> ('a -> 'b Deferred.t) -> 'b Deferred.t
