This fixes an unsafe transmute that could cause use-after-frees
on collision resolution in the headers hash and avoids allocating
for cases where it is not necessary.
Fixes#12
This introduces a bit of complexity to the example,
mainly the use of the try_continue! macro for dealing
with errors, but I think this is an appropriate trade-off
as users of this library are likely to be framework authors
instead of end users.
This allows downstream users to have total control of their concurrency
strategy, while also exposing a very nice, streaming interface for frameworks
to build on.
This also resolves issues surrounding the use of IoResult as the return type
of Handler::handle, because handlers now have complete control over how to
handle internal failure.
