Yeah. Don't you basically need this for any sort of lock-free collector 
schema?

Lets take a generic proxy gc for instance...


// Acquire Proxy
grab proxy reference
  ( store/load + store/store )


// inside gc region


// Release Proxy
  ( load/store + store/store )
drop proxy reference


acquire/release semantics are used to keep stuff contained in the garbage 
collected region...
