   flaky
      (Or "flakey") Subject to frequent lossage.  This use is of
      course related to the common slang use of the word to describe
      a person as eccentric, crazy, or just unreliable.  A system
      that is flaky is working, sort of - enough that you are
      tempted to try to use it - but fails frequently enough that
      the odds in favour of finishing what you start are low.
      Commonwealth hackish prefers dodgy.
