Subject: expect

Here
  http://www.rubygarden.org/ruby?RExpect
is a more or less drop in replacement for expect.rb with a bunch of
advantages....

  * There is a background Thread that slurps on the data source, so even
    if your foreground task is too busy, the data from the devices you are
    driving is not lost. (Doesn't matter if you are driving another
    program, matters lots if you are driving realtime devices.)
  * Reads data in large chunks instead of char by char. Therefore more
    efficient when driving a lot of devices.
  * Can log exactly what each thread saw and did.

It is multithreaded and hence prone to throw exceptions in strange places
and locking up in others. I have tweaked and synchronized until it doesn't
in my test cases and the app I'm using it for.

If you find other problems, pray do tell.

Anyone who can tell me how better to manage PTY's blasted Child_changed
RuntimeError will be blessed.
