popen() with stdout and stderr
- reading from stdout or stderr can block forever if there is no data
on that stream, but the other one has data.
A very simple solution is "bind together" the streams, such that they return
(with 0 bytes read) in case there is data only on the other stream. This
could be implemented with select/poll/epoll or similar.
