pipe(): input to, and output from, a single process
...pipe. You need to call `$write_input() again, with this
data next, usually.
* `$read_output()` returns an empty string if there is no data to
read, so typically you want to call `p$poll()` first, to make sure
that there is something to read.
* `$read_output()` might not read whole lines, so maybe
`$read_output_lines()` is better for you.
* Close the stdin of the process if you want to quit cleanly:
`close(p$get_input_connection())`.
* There is currently no way to poll the input side of the pipe. :(

pipe(): input to, and output from, a single process
hi. i'd like to instantiate sed(1), send it some input, and retrieve
its output, all via pipes (rather than an intermediate file).
my sense from pipe and looking at the sources (sys-unix.c) is that is
not possible. is that true? are there any thoughts of providing such a
facility?
cheers, Greg
