Specialized pipe class for use by `executeCommand`.

The executeCommand function needs a specialized way of interacting with a pipe. First, `executeCommand` only reads from the pipe, and never writes to it. Second, `executeCommand` needs a way to discard all output written to `stderr`, as a means of simulating the shell `2>/dev/null` construct.
