Another way to increase efficiency would be to let curl optionally
act as frontend for a "curl-agent" which does the libcurl stuff and
keeps running in the background until it hasn't been used for a
certain amount of time (or until all the state expired).

It could be enabled with an environment variable in which case
existing scripts could benefit without requiring lots of
modification, just like gpg-using scripts benefit from
GPG_AGENT_INFO being set.
