Is there interest in a std.http?

Libev is a polling abstraction. It has select, epoll and kqueue 
backends (and there may be others I don't know about). So it is 
particulary useful for unices, where epoll (linux) and kqueue 
(OSX and BSD) are preferred async IO mechanisms. It can also be 
used on Windows, but with the select() backend, which doesn't 
scale well with many file descriptors. select() is also limited 
to 64 file descriptors by default on windows IIRC (that limit can 
be raised, but only to 4096 if I am not mistaken).
