any logger in core?

[Francois Berenger]

I could create a test program.

It compiles, at least, but has the funny property of not logging anything out.

---
module Log  = Async_extra.Log

let main () =

  let logger = Log.create (Log.Level.of_string "Debug") [Log.Output.screen] in

  Log.raw   logger "%s\n" "raw log";
  Log.info  logger "%s\n" "info log";
  Log.error logger "%s\n" "error log";
  Log.debug logger "%s\n" "debug log";

  Log.close logger
;;

main()
---

Here is the oasis file for it:

I was thinking all logs would print right away.
