I describe the call chain, and why it's necessary to have the
gnutls_boot called from the C layer. If you see anything wrong with the
logic I described, please let me know.
And as I've said repeatedly, gnutls_boot is only synchronous now as a
quirk of our implementation, and making it async is the next step I am
going to take. But it's a separate issue, and will be dealt with once
the first round of changes are in.

That's why :async 'dns.
