Process::RLIMIT_NOFILE is not defined in Windows version

[tunepolo]

When using in Windows environment, net-http-persistent raise uninitialized constant error.
Maybe caused by 'Process::RLIMIT_NOFILE' in lib/net/http/persistent.rb .

# The default connection pool size is 1/4 the allowed open files.

DEFAULT_POOL_SIZE = Process.getrlimit(Process::RLIMIT_NOFILE).first / 4

net-http-persistent is used by the Ruby implementation of Selenium Webdriver, so you'll likely see this issue popping up for windows users quite often (That's why I'm here).

Experiencing the same issue!

Also experiencing this issue in Windows using Selenium Webdriver.

I also met such issue in windows using watir, any idea on fixing this?

[titusfortner]

Not that it is necessarily likely to help, but the code works fine on Windows 10, and appears to be an issue in Windows 8.

I'm running into this problem.

require 'net/http/persistent'

puts 'hello world'

What's the ETA on getting @jakauppila's pull request merged in? Still experiencing issue on Windows 10.
