  2) Is it allowed to call curl_multi_setopt on the multi handle after
calling curl_multi_perform?

As described earlier the application has a long running multi handle
with easy handels dynamically added and removed. Suppose at some point
we want to increase CURLMOPT_MAX_HOST_CONNECTIONS or enable
CURLPIPE_MULTIPLEX. Is it possible to set these options on a multi
handle in between curl_multi_perform calls? Will it only affect future
handles?

Some options aren't fully safe for dynamic changes. See
bug 1411, for example, concerning CURLMOPT_PIPELINING.
