 The signal was installed by pty, if it can't manage this signal it must
 *not* install it

n> What problems?

pigeon% cat b.rb
#!/usr/bin/ruby
require 'pty'
require 'expect'

24.times do
   PTY.spawn( "irb" ) do |pty_read, pty_write|
      pty_write.sync = true
      pty_read.expect( "irb(main):001:0> " )
      pty_write.print( "exit\n" )
   end
end
pigeon% 

pigeon% b.rb
./b.rb:6:in `spawn': Too many ptys are open (RuntimeError)
        from ./b.rb:6
        from ./b.rb:5:in `times'
        from ./b.rb:5
pigeon% 


 Manifestly it can't manage this signal
