Hmm, libcurl could maintain a "paused" flag for each easy handle, and when
that flag is set, the handle's sockets could no longer be returned in the
fd_set result of curl_multi_fdset().

I think there is a danger that timeouts, low speed limit etc will fire if
you pause something for a bit longer, the respective counters will need to
be reset when the "paused" flag is cleared.

Also, it's possible that the application will run out of connections sooner
if there's some kind of limit... What does CURLOPT_MAXCONNECTS apply to,
overall open connections, connections to a single host, or overall open,
but unused connections?

Cheers,
