Hello,

RubyInstaller's CI worker compiles and run tests for both x86 and x64 builds from trunk.

Sometimes, these builds are run in parallel and causing random (({Errno::EADDRINUSE})):

   8) Error:
 test_verify_none(TestNetHTTPS):
 Errno::EADDRINUSE: Only one usage of each socket address (protocol/network address/port) is normally permitted. - bind(2)

Full output here:

http://ci.rubyinstaller.org/job/ruby-trunk-x86-test-all/23/console

Back in #6766, Yui NARUSE used '0' as WEBrick port to select one randomly, but appears that is not working as expected.

As you can see, those random failures are a problem when trying to determine a real failure.

Perhaps the port can be randomized with (({Process.pid})) as base? That way chances of same por for different process are minimal.

Thank you.
