• Make sure you are running the bash shell.
• Run repl.rb which will echo what you print unless you enter "irb".
• Type "irb" to launch a new irb process.
• Hit Ctrl-Z to send SIGTSTP to stop the irb process.
• You'll be brought back to the main repl.
• Type "foo", hit enter. You'll be echoed "oo".
• Type "foo" again, hit enter. You'll see "foo".
• Now hit Ctrl-C to interrupt the process, it will die and the missing "f" will show up.

This seems to not be a problem with irb, but any child process that calls "gets". If you launch "irb" from bash though and do the same steps, bash doesn't exhibit this issue, just a ruby REPL.
