Builds using prepared sources that had Perl available anyway were broken
by the previous fix to this script (oops).

This change affects the makefiles checked into svn.python.org, which the 3.5
build no longer uses.  3.4 and 2.7 both still use those makefiles, but their

This change fixes a denial of service if the application is regulary

Call internal_select() with a timeout of 0 second, not a timeout of -1 second

each time data is sent successfuly. The socket timeout is now the maximum total
duration to send all data.

Use _PyTime_FromSeconds() to initialize the default socket timeout to -1
second, instead of -1 nanosecond which causes rounding issues in
internal_select().

orderable and non-orderable elements no longer depends on iteration order of
set or dict.
