How about `new_pgroup: true`? `:pgroup` option already exists and this is alike pgroup.

I created a patch attached.
- remove CREATE_NEW_PROCESS_GROUP flag by default
- add option `new_pgroup: true` to specify CREATE_NEW_PROCESS_GROUP flag

Any opinions?

Bug #6131: Ctrl-C handler do not work from exec process (Windows)

Hello,

Originally reported to TheCodeShop group: https://groups.google.com/forum/?fromgroups#!topic/thecodeshop/ZI9FY-RKYgs

The usage of "rails server" uses `exec` to spawn another process to run a server, and that process do not handle Ctrl-C.

Script to recreate this issue:

https://gist.github.com/2009356

=begin a.rb
trap(:INT) do
  puts "Hit Ctrl+C in a.rb"
end

exec "ruby b.rb"
=end

=begin b.rb
trap(:INT) do
puts "Hit Ctrl+C in b.rb"
exit(false)
end

sleep
=end

Invoking b directly from command line works, but from a.rb it fails to respond to Ctrl-C
