  o Minor features (directory, memory usage):
    - When we have recently been under memory pressure (over 3/4 of
      MaxMemInQueues is allocated), then allocate smaller zlib objects for
      small requests. Closes ticket 11791.
Use smaller zlib objects when under memory pressure We add a compression level argument to tor_zlib_new, and use it to determine how much memory to allocate for the zlib object. We use the existing level by default, but shift to smaller levels for small requests when we have been over 3/4 of our memory usage in the past half-hour.
