There was a problem hiding this comment.
I believe this was wrong @krtab. It may have been that you parsed it as:
| (None when synchro.pledges = 0) || (synchro.closed) ->Whereas it is really:
| None when ((synchro.pledges = 0) || (synchro.closed)) ->It means that if the synchronizer was closed but nonempty, then we would still return stuff from it, leading to a lot of unexpected behaviors...
The fix is to check if the synchronizer was closed first without looking at if it is empty or not.

`end_plege` is called in `work_while` when the function fails

There was a bug here: https://github.com/OCamlPro/synchronizer/pull/5/changes#r2614774996
I also added a
Fun.protectinwork_whileto make sure the pledge is ended even if the function fails. Other changes are simply cleaning.
