 // translation.  It is automatically deleted when all handles are closed
 // (or earlier -- immediately unlinked on POSIX systems).  The file is only
 // opened, once, but because both reading and writing are necessary (and in
 // different processes), the user should reset / seek back to the beginning
 // of the file between sessions.
