This comment seems unclear to me, if you don't consider the email context.

What does it mean to "stop a file", for instance?

How about:

   # Override the 'cd' builtin with a version that ensures that the
   # log file keeps pointing at the same file.  We need this because
   # unfortunately the path to the log file is recorded using an
   # relative path name, and, we sometimes need to close/reopen the log
   # after changing the current directory.  See get_compiler_info.
