(Info-goto-node "(elisp)System Environment")

Emacs maintains its own copy of the path and environment which is not visible to OCaml. Therefore, Async.Process.create will not give the same path and environment as Ecaml.Process.create, and Ecaml.System.setenv ~var:"PATH" does not affect the behavior of Async.Process.create (or Ecaml.Process.create!).
