Demonstrate best practice for feeding stdin of a child processes
It's possible to create a deadlock with stdin/stdout I/O on a single thread: * the child process may fill its stdout buffer, and have to wait for the parent process to read it, * but the parent process may be waiting until its stdin write finishes before reading the stdout. Therefore, the parent process should use separate threads for writing and reading.
