Not entirely true. The problem is that no-wait only applies when reading
data, not when opening a port, i.e. the part where the GET or POST is sent
to the server and REBOL parses the response header is blocking (done within
'open), but reading the response afterwards is non-blocking.
Core 3.0 will allow you to do all parts of an HTTP download, from the
initial DNS lookup until the port has been closed, in a non-blocking
way, using application-defined event handlers.
