A Free Software, multi-threaded, non-blocking network
application server designed for low _idle_ power consumption.
It is primarily optimized for applications with occasional users
which see little or no traffic.  yahns currently hosts Rack/HTTP
applications, but may eventually support other application
types.  Unlike some existing servers, yahns is extremely
sensitive to fatal bugs in the applications it hosts.

Changes:

    yahns 1.14.0 - removing undefined behavior

    There's minor feature removals for undocumented and
    undefined features and behavior which are unlikely to
    affect anybody unless they serve HTTPS.

    Our website is now self-hosted with HTTPS support (HTTP remains
    supported for legacy systems):

            https://yhbt.net/yahns/README

    See git history at git://yhbt.net/yahns.git for full details.

          openssl_client: avoid undefined SSL_write behavior
          move website to https://yhbt.net/yahns/
          stream_file: remove #to_io support from responses
          response: only stream "file" responses on known length
          response: fixup compile error
          req_res: do not send 502 on catchall error if response buffered

Please note the disclaimer:

  yahns is extremely sensitive to fatal bugs in the apps it hosts.  There
  is no (and never will be) any built-in "watchdog"-type feature to kill
  stuck processes/threads.  Each yahns process may be handling thousands
  of clients; unexpectedly killing the process will abort _all_ of those
  connections.  Lives may be lost!

  yahns hackers are not responsible for your application/library bugs.
  Use an application server which is tolerant of buggy applications
  if you cannot be bothered to fix all your fatal bugs.

* [PATCH] openssl_client: avoid undefined SSL_write behavior

Sometimes apps may trigger zero-byte chunks in the response
body for whatever reason.  We should maintain consistent
behavior with the rest of kgio; and Ruby OpenSSL::SSL::SSLSocket
should maintain consistent behavior with the core IO class:

 *sigh*  The pain of being an early adopter; it feels like
 nobody deployed non-blocking servers using Ruby OpenSSL
 to production before me :x
