[issue31437] test_socket.SendfileUsingSendfileTest.testWithTimeoutTriggeredSend fails due to sendfile completing before timeout

New submission from Brian Moyles:

In building Python 3.6.2 on Ubuntu 16.04, test_socket repeatedly fails at
==
FAIL: testWithTimeoutTriggeredSend (test.test_socket.SendfileUsingSendfileTest)

AssertionError: timeout not raised by _sendfile_use_sendfile

It appears this is failing as _sendfile_use_sendfile completes before the 0.01s 
timeout set in _testWithTimeoutTriggeredSend

Adjusting FILESIZE in class SendfileUsingSendTest to 100MB instead of 10MB (or 
creating FILESIZE on class SendfileUsingSendfileTest so only that set of tests 
uses a 100MB file) succeeds.

issue17085 was a similar bug from a few years ago but I'm not sure that this 
can or should be solved in the same way...
