Re: [PATCH 1/2] http.c: Use curl_multi_fdset to select on curl fds instead of just sleeping

The only problem I can see is that curl_multi_fdset is not guaranteed to 
return any fds. So in theory it could be possible that we don't get fds, but 
we're actually reading stuff. In this case things would get slow, because we 
would sleep for 50ms after every read...

However, I don't know if this is a case that actually comes up in the real 
world. Maybe Daniel has some advice on this.

It doesn't really happen so it should be safe.

The case where no fds are returned is when libcurl cannot return a socket to 
wait for during name resolving (if your particular libcurl is built to use 
such a resolver backend - libcurl has several different ones). And during name 
resolving there won't be any data to read for the libcurl-app anyway.
