  Scratch the git_revp_attr configuration of a git_revp
  
  This isn't the best idea I've head.  Pierre Habouzit was suggesting
  a technique of assigning a unique integer to each commit and then
  allocating storage out of auxiliary pools, using the commit's unique
  integer to index into any auxiliary pool in constant time.  This way
  both applications and the library can efficiently attach arbitrary
  data onto a commit, such as rewritten parents, or flags, and have
  them disconnected from the main object hash table.
