Oh, how i wish it was that simple... i got my non-blocking mojo (haha!)
from actually implementing event loops... and it took me quite a while of
looking like a fool to really grok it.
The simplest implementation i know of is actually the fallback event loop
in Mojolicious. If you understand that module i'm pretty sure you
understand non-blocking.

I've been desperately looking for a good tutorial to point people at, but
without much success so far.

Well, i guess then i have no choice but to answer. :)
It's all about the underlying syscalls, here's a pretty decent explanation
i just found.

Most DBI drivers for example made the choice to use blocking syscalls, and
we can't change that from the outside. (There are certain hacks, but they
all have their drawbacks)
