module Async_sys: sig .. end
This module overrides everything in the Sys module that might block. Functions do
the same thing as their counterparts in Sys, but instead return deferreds. For a
description of the semantics of their semantics see the documentation for the Sys
module.

val file_exists_exn : string -> bool Import.Deferred.t
val when_file_exists : ?poll_delay:Core.Std.Time.Span.t -> string -> unit Import.Deferred.t
when_file_exists ?poll_delay file returns a deferred that becomes determined when
file exists. The default poll delay is 0.5 seconds. It raises an exception if it
can not check whether the file is there, in the same cases file_exists returns
`Unknown.
