Hey all,

I've got a pull request at https://github.com/php/php-src/pull/15603
that I wanted to bring to your attention. We're interested in being
able to reuse curl share handles across requests in mod_php, since
we'd expect a performance benefit from not having to redo DNS lookups
(in the case of CURL_LOCK_DATA_DNS) or having to re-establish
connections (in the case of CURL_LOCK_DATA_CONNECT).

I'm not tied to the specific implementation in my PR, though I'll note
that I ran into an issue with calling curl_share_setopt with
CURL_LOCK_DATA_CONNECT that makes it preferable to be able to
initialize the curl share handle once with the share options. I've
fixed that issue in https://github.com/curl/curl/pull/14696, but of
course that won't be available for most people for quite some time.

Thanks!
Eric Norris
