Add Windows debug Makefile workaround. (#9)

* retain --debug and other flags when debug is used and is not windows

* this addtional thing is temporary

* provide some extra grace for windows 3.11

* lets bump it to 0.015 instead so that 3.12 windows has some chance of winning

* give a bigger buffer and shorter timeout on windows.

* readjust timeout of test_socket_cancel_sendall

* mark windows as both winning and loosing this test it's an unwanted coinflip.

* final straw for test_socket_cancel_sock_sendall

* test_call_later_2 time decrease

* last but not least
