t/nonblock.t test fails on armv6l

[kiwiroy]

Both the multiple write attempts tests fail for me on a single processor RaspberryPi under the following conditions. System perl (same versions) on a multi processor Pi results in successful test with and without patch.

software	system perl	perlbrew
perl	v5.24.1	v5.26.2
Net::SSLeay	1.80	1.85
URI	1.71	1.74

My current workaround is doubling the sleep time on line 336

There were fixes to t/nonblock.t in 2.071. Hopefully this fixes this problem too. If not please reopen or create a new issue with the new output from prove -lv t/nonblock.t since I've added more detailed debugging output.
