  Also, the text for recvfrom told you to read recv() for an explanation of the

  man-page text to recvfrom(), recvfrom_into, recv_into to avoid the pointless
  redirection.

  [Apply length-checking.diff from bug #1599254]

  Add length checking to single-file mailbox formats: before doing a
  flush() on a mailbox, seek to the end and verify its length is
  unchanged, raising ExternalClashError if the file's length has
  changed.

  This fix avoids potential data loss if some other process appends to
  the mailbox file after the table of contents has been generated;
  instead of overwriting the modified file, you'll get the exception.

  I also noticed that the self._lookup() call in self.flush() wasn't
  necessary (everything that sets self._pending to True also calls
  self.lookup()), and replaced it by an assertion.

  2.5 backport candidate.

  exception.  (<crossing fingers for the buildbots>)

"""CGI-savvy HTTP Server.
This module builds on SimpleHTTPServer by implementing GET and POST
requests to cgi-bin scripts.
If the os.fork() function is not present (e.g. on Windows),
os.popen2() is used as a fallback, with slightly altered semantics; if
that function is not present either (e.g. on Macintosh), only Python
scripts are supported, and they are executed by the current process.
In all cases, the implementation is intentionally naive -- all
requests are executed sychronously.
SECURITY WARNING: DON'T USE THIS CODE UNLESS YOU ARE INSIDE A FIREWALL
