  Issue #11224: Improved sparse file read support (r85916) introduced a
  regression in _FileInFile which is used in file-like objects returned
  by TarFile.extractfile(). The inefficient design of the
  _FileInFile.read() method causes various dramatic side-effects and
  errors:

    - The data segment of a file member is read completely into memory
      every(!) time a small block is accessed. This is not only slow
      but may cause unexpected MemoryErrors with very large files.
    - Reading members from compressed tar archives is even slower
      because of the excessive backwards seeking which is done when the
      same data segment is read over and over again.
    - As a backwards seek on a TarFile opened in stream mode is not
      possible, using extractfile() fails with a StreamError.

  Issue #11074: Make 'tokenize' so it can be reloaded.

  The module stored away the 'open' object as found in the global namespace
  (which fell through to the built-in namespace) since it defined its own 'open'.
  Problem is that if you reloaded the module it then grabbed the 'open' defined
  in the previous load, leading to code that infinite recursed. Switched to
  simply call builtins.open directly.

  Issue #10992: make tests pass when run under coverage.

  Various tests fail when run under coverage. A primary culprit is refcount tests
  which fail as the counts are thrown off by the coverage code. A new decorator
  -- test.support.refcount_test -- is used to decorate tests which test refcounts
  and to skip them when running under coverage. Other tests simply fail because
  of changes in the system (e.g., __local__ suddenly appearing).

  Thanks to Kristian Vlaardingerbroek for helping to diagnose the test failures.

  Issue #10990: Prevent tests from clobbering a set trace function.

  Many tests simply didn't care if they unset a pre-existing trace function. This
  made test coverage impossible. This patch fixes various tests to put back any
  pre-existing trace function. It also introduces test.support.no_tracing as a
  decorator which will temporarily unset the trace function for tests which
  simply fail otherwise.

  Thanks to Kristian Vlaardingerbroek for helping to find the cause of various
  trace function unsets.
