huh, one might think that would have been helpful to mention up front.
Now that we have come full circle I will point you once again back to
the docs, and this time specifically the C<waitfor> method and the list
of 3-4 examples at the bottom of the docs that talk about how to
interact with a program, specifically the ssh example and the passwd
example. This should allow you to turn off the timeout, or at least set
it to something arbitrarily high.
