 https://github.com/arlolra/check
 is a (not yet completed) rewrite of TorCheck.py but it comes with its own
 webserver -- which should help both the "the cgi has to parse a bunch of
 stuff on startup each time" problem and the "oh my god we're running how
 many apaches" problem (which are related).

 To do the replacement though, we need to enumerate all the things that
 check.tp.o serves right now.

 Here's a start:
 A) The index page, including variants of it like
 https://check.torproject.org/?lang=en-US&small=1&uptodate=1 that TBB 2.x
 use as their homepage. Apparently there's also a /?TorButton=true variant
 too.

 B) https://check.torproject.org/RecommendedTBBVersions (a flat text file
 that gets fetched by millions of people)

 C) https://check.torproject.org/cgi-bin/TorBulkExitList.py which is
 another cgi that should eventually get rewritten. (Its current design is
 particularly painful because of the number of dns queries it launches.)

 D) https://exitlist.torproject.org/exit-addresses used to be the static
 file that tordnsel exports. It's currently 403'ed by webserver
 configuration, since some jerks are scraping it at maximum speed. But I'd
 like to expose it again someday. I mention exitlist because it's on the
 same apache as check currently, but there's no reason it necessarily needs
 to move at the same time.

 Currently we run tordnsel on the same machine as check, since the check
 cgi's do dns queries and it's best to do those over localhost. I'd like to
 move tordnsel elsewhere though, to better partition things. We can do that
 only once none of the check processes do these dns queries.
