pgroup => true problematic with rerun use

[dentarg]

#1 added the pgroup => true option to Process.spawn

overman/lib/foreman/process.rb

Lines 48 to 57 in 96002f8

	def run(options={})
	env = @options[:env].merge(options[:env] || {})
	output = options[:output] || $stdout
	runner = "#{Foreman.runner}".shellescape
	pgroup = Foreman.windows? ? :new_pgroup : :pgroup
	Dir.chdir(cwd) do
	Process.spawn env, expanded_command(env), :out => output, :err => output, pgroup => true
	end
	end

That makes this chain stop working: overman -> rerun -> overman -> <app>

rerun prints [rerun] <app> launched but it is never started

Not sure if it depends on what flags you pass to rerun, I should post a repro here. I've been using rerun 0.14.0.
