内存缓存 Memcached 1.4.17 发布。2013-12-21 上一个版本是 2012-12-09 的 1.4.16 。此版本在 Linux 上支持了 accept4()，去掉每个 tcp 连接的 syscall，增加 -F 参数可以禁止 flush_all 命令。 scripts/memcached-tool 支持 "settings" 和 "sizes" 命令及一些 Bug 修正。
完全改进：Fixes
Fix potential segfault in incr/decr routine.
Fix potential unbounded key prints (leading to crashes in logging code)
Fix bug which allowed invalid SASL credentials to authenticate.
Fix udp mode when listening on ipv6 addresses.
Fix for incorrect length of initial value set via binary increment protocol.
新特性：
Add linux accept4() support. Removes one syscall for each new tcp connection.
scripts/memcached-tool gets "settings" and "sizes" commands.
Add parameter (-F) to disable flush_all. Useful if you never want to be
able to run a full cache flush on production instances.
