There's a huge different between those two suggestions. The assigned priority
will assume the programmer/user knows what connections that are important to
keep persistant before-hand, while the callback approach lets the
programmer/user decide no earlier than exactly when there's a need to re-use
a connection.

The callback approach doesn't exclude the first approach, it only forces the
assignment to be kept outside of libcurl.

I think it would be useful if we could come up with actual use-cases for
these things, but I fear that will be tricky and that we'll have to pick one
(or both) pretty much on gut-feeling. Nothing different from normal that is!
;-)

Anyone else with opinions or ideas on this?
