37205 ** Proxy locking is a "uber-locking-method" in this sense: It uses the
37206 ** other locking methods on secondary lock files. Proxy locking is a

37265 ** a proxy path based on the user's temp dir
37267 ** actual proxy file name is generated from the name and path of the

37274 ** be removed, however it may be switched to a different proxy path via
37279 ** How proxy locking works
37282 ** Proxy file locking relies primarily on two new supporting files:
37287 ** * proxy file to act as a proxy for the advisory locks normally
37290 ** The conch file - to use a proxy file, sqlite must first "hold the conch"
37293 ** proxy path against the values stored in the conch. The conch file is
37297 ** host ID and/or proxy path, then the lock is escalated to an exclusive
37298 ** lock and the conch file contents is updated with the host ID and proxy
37303 ** The proxy file - a single-byte file used for all advisory file locks
37308 ** Requesting the lock proxy does not immediately take the conch, it is
37315 ** The proxy file and the lock file are never deleted so they only need
