<p>Special asynchronous methods missing in <code>Zlib::GzipWriter</code>. <code>rewind</code> wants to <code>close</code>, <code>close</code> wants to <code>write</code> something and <code>flush</code>, <code>flush</code> want to <code>write</code> something. So it is possible to have asynchronous variants for these synchronous methods. Behaviour is the same as <code>IO#write_nonblock</code> meth
