Hmmm, this expiration is what I was trying to avoid with my last question :)
Are you planning to implement more formal locks in memcached (when?) or is this still just an idea ?

Long enough that it's not possible for the original process to still be processing after setting the lock. Ghetto locks :) -Dormando
