But the keys retrieved could still be wiped out.

1.  start tx
2.  retrieve(k1, k2, k3)
3.  // go make coffee; other processes changing stuff, which removes  
keys from the L1, negating the effect of step 2
4.  replace(k1, v1) // will return incorrect retval.  Or will need to  
do a remote get again at this point
5.  end tx
