This depends on '%CURL_SSL_BACKEND' too.
With 'openssl', I get similar to the above.
Oh yes thanks, I forgot to mention that. I used the same OpenSSL version (and
the same set of other depedencies as well) in all my builds.
OpenSSL is one of the three TLS backends that use that function I optimized.
But with 'schannel', I get:
Allocations: 579 Maximum allocated: 811709
The schannel TLS backend is notoriously "mallocy", to the extent that I added
13.7 to the TODO recently: "Less memory massaging with Schannel":

If you download or upload large content, you'll see it hit the roof in a way
it really shouldn't.
