Excellent!

A few immediate pointers:

1 - join and discuss details and implementation on the curl-library list, as
     that's where all the libcurl hacking is done. This list (curl-and-php) is
     for the PHP binding. (and I'm not a PHP guy, really)

2 - The API to share connections between handles would be done using the share
     interface. Read up how it works today and how it can already share things
     between handles as a good introduction.

3 - See 'struct conncache' and lib/conncache.[ch] for the implementation
     details on how the connection cache works. You basically need a way to
     lock the access and exclusively extract a connection for use, so that
     multiple independent handles can be made to share a single pool.
