I am having a source/sink API for that, that supports different types
of sources/sinks (buffer, file, filter, composite, ...) which I am 
pretty proud of.
However, I got told that my current sendfile() use is not ideal, as it is 
indeed nonblocking for the target fd but the source fd (on-disk file)
it still may block. Which is something I have to work around
once the x0 core matures.

I like the idea of memory pools, too, however, I am using a slightly different 
approach for at least request buffer(s) and their extracted values, where I 
keep the whole request in a single buffer and let field values just reference 
the sub sections (offset + count) to reduce the number of malloc/memcpy/free 

Happy eastern!
