#@492 Makes it possible to cache data in FILE.
Creates any necessary parent directories, deleting any non-directory files
that would stop this. Returns nil if parent directories can not be
created. If FILE already exists as a non-directory, it changes
permissions of FILE or deletes FILE to make it possible to write a new
version of FILE. Returns nil if this can not be done, or if FILE already
exists as a directory. Otherwise, returns t, indicating that
FILE can be created or overwritten.
