How about adding a module that offers a builtin that behaves like
a mixture of `coproc' and `eval' (i.e. arguments used as by `eval',
otherwise like `coproc') but executes the stuff in a pty?

This could also support options for simplifying parsing the output (so 
that we don't have to read one character after another but instead can 
read them in blocks, making things faster).

Any portable-pty-code experts around here?
