// Works around BXC #3801 - Managed Container subclasses are incorrectly resurrected, then leak.
// It does this by registering an alternative callback for gtksharp_container_override_forall, which
// ignores callbacks if the wrapper no longer exists. This means that the objects no longer enter a
// finalized->release->dispose->re-wrap resurrection cycle.
// We use a dynamic method to access internal/private GTK# API in a performant way without having to track
// per-instance delegates.
