Looks like d8a7d3e5 just didn't get in the release.  I think it should
have worked.  Further debugging suggests this problem starts when
create-thread initializes a new (editor) thread.  I can cause a
problem just with:

    (create-thread #f (lambda () unspecific))

and avoid it by resetting the default-environment.  E.g. this works:

    (ge '(runtime floating-point-environment))
    (initialize-package!)
