Issue #19928: Fix test on Windows
Issue #18270: Prevent possible IDLE AttributeError on OS X when no initial
shell window is present. (Original patch by Terry Reedy)
Issue #18270: merge from 3.3
Fixes Issue #17200: telnetlib's read_until and expect timeout was broken by the
fix to Issue #14635 in Python 3.3.0 to be interpreted as milliseconds instead
of seconds when the platform supports select.poll (ie: everywhere).  It is now
treated as seconds once again.
null merge (3.4 doesn't need this fix)
Issue #18864: Add a setter for ModuleSpec.has_location.
