I’ve noticed 2 bugs when implementing memcache session.handler for

session.save_handler = memcache  
session.save_path = "tcp://127.0.0.1:11211"  

1. With memcache.protocol = ascii, there is some random lock on session_start() according to memcache.lock_timeout
   so i've set memcache.lock_timeout = 1 but that doesn’t resolve the problem (just makes it less visible..)
2. With memcache.protocol = binary, first bug seems not appearing but session destroy failed !
   All that test have been done with phpmyadmin which write complex data in session

So you can find MemcacheSessionHandlerPrepend.php a MemcacheSessionHandler implementing SessionHandlerInterface to add to your php.ini with config:

session.save_handler = user  
auto_prepend_file = c:/path/to/MemcacheSessionHandlerPrepend.php  
; session.save_path =
