1.7 Detect when called from within callbacks
1.8 CURLOPT_RESOLVE for any port number
1.9 Cache negative name resolves

1.11 minimize dependencies with dynamically loaded modules
1.12 have form functions use CURL handle argument
1.14 Typesafe curl_easy_setopt()
A name resolve that has failed is likely to fail when made again within a
short period of time. Currently we only cache positive responses.

1.11 minimize dependencies with dynamically loaded modules
We can create a system with loadable modules/plug-ins, where these modules
