This looks like an issue ... I think EagerLoad is not compatible with
non-singleton scopes.
What does it mean to eager load a service that is, in fact, used in
multiple threads?
Ah, here's the issue; when you bind a class, not an interface, as a
service, it automatically uses singleton scope. Only proxiable
services can have non-singleton scope, and that means an interface and
an implementation. Tapestry should detect this and throw an
exception.
