After upgrading from jruby 9.1.14.0 to 9.1.15.0 we have realized that the upgrade seems to have caused a regression with TCPSocket#close_on_exec (see #4858)

This causes selenium-webdriver (3.7.0) and childprocess (0.8.0) to not work as before...

https://github.com/SeleniumHQ/selenium/blob/selenium-3.7.0/rb/lib/selenium/webdriver/common/socket_lock.rb#L61-L62

https://github.com/enkessler/childprocess/blob/0bce27d3f84ffac06ee49aa4dcb9ce8608cc49d3/lib/childprocess.rb#L153-L156

This combination raises an exception (on windows) —

More fallout from defining O_CLOEXEC but not having it fully supported along all paths.

I think IO#close_on_exec= should at worst silently fail to set the flag.
