-/*
- This class is the entry point to stumbling, in that it
- receives the location+cell+wifi string and writes it
- to disk, or instead, it calls UploadStumbleRunnable
- to upload the data.
-
- Writes will happen until the file is a max size, then stop.
- Uploads will happen only when the file is one day old.
- The purpose of these decisions is to have very simple rate-limiting
- on the writes, as well as the uploads.
-
- There is only one file active; it is either being used for writing,
- or for uploading. If the file is ready for uploading, no further
- writes will take place until this file has been uploaded.
- This can mean writing might not take place for days until the uploaded
- file is processed. This is correct by-design.
-
- A notable limitation is that the upload is triggered by a location event,
- this is used as an arbitrary and simple trigger. In future, there are
- better events that can be used, such as detecting network activity.
-
- This thread is guarded so that only one instance is active (see the
- mozilla::Atomics used for this).
