Now that we support IO::Poll once again, we can remove
the IO::KQueue requirement.

We'll likely replace IO::KQueue (at least on FreeBSD) using
a pure-Perl syscall()-based version since syscall numbers are
consistent across architectures on FreeBSD and easy to maintain.
IO::KQueue->EV_SET is also shockingly inefficient in that it
calls kqueue() as much as epoll_ctl.

I finally took the step of making changes to DS after
wanting to do something along these lines to Danga::Socket
for the past decade or so And down the rabitt-hole I went.
Write buffering now goes to the filesystem (which is quite fast
on Linux and FreeBSD), so memory usage with giant messages is
slightly reduced compared to before. It could be better if we
replace Email::(Simple|MIME) with something which doesn't
require slurping (but that's a big task).
Fields for read (for NNTP) and all write buffers are lazily
allocated, now, so there's some memory savings with 10K clients
Further memory savings were achieved by passing $self to
DS->write(sub {...}), eliminiating the need for most anonymous
subs.
NNTPS and NNTP+STARTTLS are now supported via public-inbox-nntpd
using the --key and --cert parameters (HTTPS coming). I'm very
happy with how I was able to reuse the write-buffering code for
TLS negotiation and not have to add additional fields or code in
hot paths.
I'm pretty happy with this, so far; but there's still plenty
left to be done. I'm not too impressed with the per-client
memory cost of IO::Socket::SSL, even with
SSL_MODE_RELEASE_BUFFERS, and will need to do further analysis
to see what memory reductions are possible.
