37266 ** Proxy file locking relies primarily on two new supporting files:
37271 ** * proxy file to act as a proxy for the advisory locks normally
37274 ** The conch file - to use a proxy file, sqlite must first "hold the conch"
37277 ** proxy path against the values stored in the conch. The conch file is
37281 ** host ID and/or proxy path, then the lock is escalated to an exclusive
37282 ** lock and the conch file contents is updated with the host ID and proxy
37287 ** The proxy file - a single-byte file used for all advisory file locks
37292 ** Requesting the lock proxy does not immediately take the conch, it is
