Hi,

Prior to 2.0.0dev, this script:

sasha:rubinius brian$ cat process.rb 
puts "before system"
system("ruby -e 'Process.kill(:HUP, 0)'")
puts "after system"

would print the following:

sasha:rubinius brian$ ruby1.9.2 -v process.rb 
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin10.8.0]
before system
after system

Basically, SIGHUP was ignored when sent from a subprocess. Presently, this is the result:

sasha:rubinius brian$ ruby -v process.rb 
ruby 2.0.0dev (2011-11-01 trunk 33596) [x86_64-darwin10.8.0]
before system
Hangup

The following issue may be related, but the explanation is in Japanese, so I cannot follow it: http://redmine.ruby-lang.org/issues/4765

Is this change intentional? I discovered it running RubySpec, where there are specs for the behavior of sending SIGHUP to the process group.

Thanks,
Brian
