High CPU when stopping the Clojure server

[oubiwann]

1. Start the clojure REPL
2. Start the clojure server (managed-server)
3. Call the stop function (from either the LFE or Clojure API)
4. Watch the CPU jump to post 100%

It seems that stopping only really works when you run the clojure server from (-main); looks like the core.async loop in (managed-server) isn't written correctly.

There's a new core.async release that fixes a related issue (and might well fix the issue underlying this bug).

That being said, I think the source of the problem is actually an incorrect placement of a recur inside or outside an if/when block ...
