Lots of process-related stuff can be eliminated.

It's unused.

No one actually listens to these notifications.

The purpose of all this code is to call OnWaitableEventSignaled at the right time. But all the implementations of these methods are no-ops.

No one uses it.

We only send messages on a channel, so this interface is pointless.

No one uses this info.

These are unused now that the notification service is gone.

Only one of these is ever used.

More unused stuff here.
