Comment:

 This is done:

 {{{

 <duncan at community.haskell.org>
   * Add a source package index cache to speed up reading
   e.g. about 3x faster for cabal info pkgname
 }}}

 Some timings using a list of all packages from Hackage (~4000 packages):

    * with cabal-install-0.10.2: more than 8 minutes (didn't wait for it to
 finish)
    * with cabal-install-0.13.3: 2 minutes 44 seconds
    * with cabal-install-0.13.3 and modular solver: 49 seconds

 Of course, this package list results in an error.
