  ## These tests are currently very implementation-specific, and they rely heavily on
  ##  having access to the "disable_lockfile" method.  However, I've made this method private
  ##  because it really shouldn't be exposed outside of our implementation... therefore
  ##  these tests have to use a lot of ".send" calls.  They should probably be cleaned up
  ##  but for the moment I wanted to make sure not to lose any of the functionality of
  ##  the tests. --cprice 2012-04-16
