val flush : unit -> unit IO_flush.t: Flush whatever need to be to get pending output out on file descriptor 0.

val run : (unit -> unit IO_run.t) -> unit: Run an IO operation until completion

val flushed : unit -> bool: Synchronous check that there is no pending output on file description 0. With async, there is no guarantee that on the rhs of a IO.bind (flush ()) ... the output is completely flushed, that's why we need this.

val upon_unreleasable_issue : Expect_test_config_types__.Expect_test_config_types_intf.Upon_unreleasable_issue.t: upon_unreleasable_issue specifies how to deal with output that should not be released even if it is accepted (e.g. backtraces). The default is `CR.
