Thanks for pointing this out.
I apparently misunderstood this paragraph as a hint of how libcurl works
internally (that it simply won't reuse the underlying connection) rather than
"application MUST NOT pass such easy handle to curl_easy_perform again".
So let's say I call curl_easy_cleanup + curl_easy_init before each
reconnection. Will libcurl reuse old TLS context and resolver cache?
