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: MOAR SLEEPY
On responses with a known, non-zero Content-Length, yahns will now
automatically use the MSG_MORE flag when sending HTTP headers. This
reduces TCP packet transmits and allows clients to wake up and read
one less time.
This is similar to the TCP_NOPUSH/TCP_CORK functionality of other
servers, but requires no additional syscalls. It is only supported
on the Linux kernel, however (but yahns is currently epoll-only
with kqueue support on the horizon).

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.
