-FIXME Getting this sometimes
-Failed to copy: Upload failed: invalid character '<' looking for beginning of value
-This is a JSON decode error - from Update / UploadByChunk
-- Caused by 500 error from dropbox
-- See https://github.com/stacktic/dropbox/issues/1
-- Possibly confusing dropbox with excess concurrency?

-FIXME implement timeouts - need to get "github.com/stacktic/dropbox"
-and hence "golang.org/x/oauth2" which uses DefaultTransport unless it

-func (db *Dropbox) client() *http.Client {
-	return db.config.Client(oauth2.NoContext, db.token)
-}

-// HTTPClient is the context key to use with golang.org/x/net/context's
-// WithValue function to associate an *http.Client value with a context.
-var HTTPClient ContextKey
-
-So pass in a context with HTTPClient set...
