Once per lifetime of the application.

Yes

Doesn't matter, it is a global init.

Nope.

You shouldn't call curl_global_init for each thread, but you should call
curl_global_cleanup once for each time you called curl_global_init.

Perhaps, I don't think we're willing to guarantee that it won't ever be one
even if I think you won't leak memory now since only the first call to
curl_global_init will actually do anything and the following ones are just
increasing a counter.
