 # Atomicness
 
-When it comes ot atomicness, the biggest challenge is to check "item exists" and "item not expired" in one go.
-
-When an item was "found but is expired" - we need to treat this as "not found" and discard it. For that we either need to use a lock
-so that the the three steps "exist? expired? remove!" are performed atomically. Otherwise another tread might chip in,
-and ADD a non-expired item with the same key while we're evicting it. And we'll be removing a non-expired key taht was just added
-
-OR instead of using locks we can remove _by key AND by value_. So if another thread has just rushed in 
-and added another item with the same key - that other item won't be removed.
-
-basically, instead of doing this
-
-```
-lock {
-	exists?
-	expired?
-	remove by key!
-}
-```
-
-we do this
-
-```
-exists? (if yes returns the value)
-expired?
-remove by key AND value
-```
-
-If another thread chipped in while we were in the middle of checking if it's expired or not, and recorded a new value - we won't remove it.
-
-Locks suck becasue add extra 50ns to benchmark, so it becomes 110ns instead of 70ns which sucks.
-So - no locks then!
