That's a little bit of a problem if you have multiple expect objects (using '-i').
Which one should it get?  Should multiple timeout handles be allowed, one for
each '-i'?  I was in a hurry and decided to make timeout handlers global
to all expect objects in that expect() call.

Right.  And it also works for multiple expect objects.  I will put that into
the docs...

You're right, the whole code could use a lot of cleanup.  But as Expect2
is becoming a possibility, anything invested here is wasted.

Not at all!  Constructive criticism is always welcome.
