popen() uses FILE streams, which I at least try to avoid. For example in some systems (Solaris IIRC) they were limited to 256 first file descriptors.
It also executes everything through /bin/sh -c, which is pointless if you're not running a script and possibly dangerous if you're not escaping parameters correctly.
