  Buffer11: Use adaptive threshold for releasing system memory.
  
  The hard-coded threshold of five uses before a release was regressing
  the Oort online benchmark, which seems to use an index buffer many
  times, then change to a different range of indices, which would need
  to check the system memory for index range validation.
  
  Also add a performance regression test, and an update to the perf
  runner script which checks for the most recent binary among the search
  directories.
