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.

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
