4.0.0

• 4.0.0 - May 20 2017

• Fixup short delay after a thread times out

• Fix where in some cases (depending on what was execution when abort was

called), a default handler could print the tracback to stderr outside of the
scope of the normal raise (it would still be raised, just handled twice).

• Add a function decorator which provides a default timeout, allows that
  timeout to be overriden by adding a "forceTimeout" kwarg to the function
  (configurable), or even running a function to calculate the timeout based on
  args for each call

• Some improvements to python2 support

• Add GoodTests (Unit tests)
