Bug description

For some reason GC collects react events borrowed in Lwt_react.E.select. Lwt_react in flambda build.E.keep or saving event in some variable or reference does not help either. Without flambda GC does not collect values it seems.

Steps to reproduce

A trivial example is attached. With flambda switch Lwt_react.E.with_finaliser functions print, without flambda they do not.
