Even if this answer might be coming late: this comment is outdated. The
fullduplex code (for netconn and sockets) has been changed a great deal
and this comment has been removed some time ago.

What you're looking at is the "old" code of the last release. Try the
git master branch instead.

A release on that code base should follow soon...
