.. master:: void preload(string file)

  Load the object with the given file name (which was returned by :master:`epilog`). It is the task of the :master:`epilog`/:master:`preload` pair to ensure the validity of the given strings (e.g. filtering out comments and blank lines). For preload itself a ``call_other(file, "???")`` is sufficient, but it should be guarded by a :efun:`catch` to avoid premature blockings. Also it is wise to change the master's euid from root_uid to something less privileged for the time of the preload.

  You can of course do anything else with the passed strings--preloading is just the traditional task.
