Seems like the current version of lwt-equeue does not run threads at top of ocamlnet
This program works at older version 0.2.1 of orpc but not with the trunk of lwt-equeue. (Note that the old version is also using ocaml 3.11.1 and the new version is running using 3.12, but I guess that is not the cause of the problem):
open Lwt
let rec do_something () =
Lwt_unix.sleep 1.0 >>= fun _ ->
Printf.printf "*%!";
do_something ()

let esys = Unixqueue.create_unix_event_system ();;
let _ =
Lwt_equeue.set_event_system esys;
ignore(do_something ());
Unixqueue.run esys;
;;

I'm able to run Lwt threads that are linked agains lwt-equeue with the latest version by running them as lwt thread:
open Lwt

let rec do_something () =
Lwt_unix.sleep 1.0 >>= fun _ ->
Printf.printf "*%!";
do_something ()

let esys = Unixqueue.create_unix_event_system ();;
let _ =
Lwt_equeue.set_event_system esys;
Lwt_unix.run (do_something ());
;;

And this can be done without creating or setting the event system, so I guess they are run fully outside ocamlnet.

Also I got a problem when compiling lwt-equeue the first time. It wants to compile cohttpserver-netplex that is dependent on lwt-equeue which is not yet installed.

Hi,

Lwt 2.2 has changed form select based to using libev. As part of this they seem to have dropped support for low level control of event loop in Lwt_main. Do you think this might result in that lwt-equeue will no longer work for newer versions of Lwt or is there other ways to still make it working?

Thanks,

Hans Ole
