Just to put this thread to rest:
I ended up implementing CA-Bundle caching by myself and using CURLOPT_SSL_CTX_FUNCTION to inject it
into the SSL context. Works like a charm.
Switching the code to connection pooling is a nightmare in the current state of the code, so it'll have to wait,
even though the connection phase is what dominates the profile at the moment.
Thank you all for the comments.
