Or a third option: Should the plugin open a new cURL handle for every
request?

Or a fourth: Keep open a collection of cURL handles? (And if so, what
policy to use to decide when to open a new handle or close an old one?)

Note that NBD pread & pwrite requests are generally quite small,
frequent, and of course unpredictable in both size, frequency and
order.
