// This first principle is that if we're going to suspend when we complete
// a root, then we should also restart if we get an update or ping that
// might unsuspend it, and vice versa. The only reason to suspend is
// because you think you might want to restart before committing. However,
// it doesn't make sense to restart only while in the period we're suspended.
//
// Restarting too aggressively is also not good because it starves out any
// intermediate loading state. So we use heuristics to determine when.
// Suspense Heuristics
//
// If nothing threw a Promise or all the same fallbacks are already showing,
// then don't suspend/restart.
//
// If this is an initial render of a new tree of Suspense boundaries and
// those trigger a fallback, then don't suspend/restart. We want to ensure
// that we can show the initial loading state as quickly as possible.
//
// If we hit a "Delayed" case, such as when we'd switch from content back into
// a fallback, then we should always suspend/restart. Transitions apply
// to this case. If none is defined, JND is used instead.
//
// If we're already showing a fallback and it gets "retried", allowing us to show
// another level, but there's still an inner boundary that would show a fallback,
// then we suspend/restart for 500ms since the last time we showed a fallback
// anywhere in the tree. This effectively throttles progressive loading into a
// consistent train of commits. This also gives us an opportunity to restart to
// get to the completed state slightly earlier.
//
// If there's ambiguity due to batching it's resolved in preference of:
// 1) "delayed", 2) "initial render", 3) "retry".
//
// We want to ensure that a "busy" state doesn't get force committed. We want to
// ensure that new initial loading states can commit as soon as possible.

// different layout, where the child points to a dehydrated fragment, which

//
