-// ForceTLSState maintains an in memory database containing the list of hosts
-// that currently have ForceTLS enabled. This singleton object deals with
-// writing that data out to disk as needed and loading it at startup.
-
-// At startup we need to load the ForceTLS state from the disk. For the moment,
-// we don't want to delay startup for this load, so we let the ForceTLSState
-// run for a while without being loaded. This means that it's possible for
-// pages opened very quickly not to get the correct ForceTLS information.
-//
-// To load the state, we schedule a Task on the file thread which loads,
-// deserialises and configures the ForceTLSState.
-//
-// The ForceTLSState object supports running a callback function when it
-// changes. This object registers the callback, pointing at itself.
-//
-// ForceTLSState calls...
-// ForceTLSPersister::StateIsDirty
-// since the callback isn't allowed to block or reenter, we schedule a Task
-// on |file_thread_| after some small amount of time
-//
-// ...
-//
-// ForceTLSPersister::SerialiseState
-// copies the current state of the ForceTLSState, serialises and writes to
-// disk.
