Is the following expected?

$ irb

=> #<Process::Status: pid 20110 exit 0>

What are those phantom processes?
-r

What platform are you on? What ruby version? For me, with ruby
1.8.7.249-2 standard package from Ubuntu Lucid amd64:

$ irb
irb(main):001:0> $?
=> nil
irb(main):002:0> $?
=> nil
irb(main):003:0> $?
=> nil
irb(main):004:0> RUBY_VERSION
=> "1.8.7"

On windows it appears to behave as expected.

On linux (Ubuntu, I believe latest revision).

All built from source:

[25:1557][rdp(a)ilab1:~]$ ruby -v
ruby 1.9.1p243 (2009-07-16 revision 24175) [i686-linux]
[25:1557][rdp(a)ilab1:~]$ export RUBYOPT=
[25:1558][rdp(a)ilab1:~]$ irb
irb(main):001:0> $?
=> #<Process::Status: pid 21719 exit 0>
irb(main):002:0> $?
=> #<Process::Status: pid 21731 exit 0>
irb(main):003:0> $?
=> #<Process::Status: pid 21743 exit 0>
irb(main):004:0> exit
[25:1558][rdp(a)ilab1:~]$ ~/installs/ruby-1.8.7-p174_installed/bin/irb

Is there something in your .irbrc that is firing off processes?

Linux or Windows, all the versions return nil when asked.

Seems there is a thread you're running with your irb session that
might be spawning a lot.
