  [Bug #1497414] _self is a reserved word in the WATCOM 10.6 C compiler.
  Fix by renaming the variable.

  In a different module, Neal fixed it by renaming _self to self.  There's
  already a variable named 'self' here, so I used selfptr.

  (I'm committing this on a Mac without Tk, but it's a simple search-and-replace.
  <crosses fingers>, so  I'll watch the buildbots and see what happens.)

  In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
  to each allocated block.  This was using 4 bytes for each such
  piece of info regardless of platform.  This didn't really matter
  before (proof: no bug reports, and the debug-build obmalloc would
  have assert-failed if it was ever asked for a chunk of memory
  >= 2**32 bytes), since container indices were plain ints.  But after
  the Py_ssize_t changes, it's at least theoretically possible to
  allocate a list or string whose guts exceed 2**32 bytes, and the
  PYMALLOC_DEBUG routines would fail then (having only 4 bytes
  to record the originally requested size).

  Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
  build's extra debugging fields.  This won't make any difference
  on 32-bit boxes, but will add 16 bytes to each allocation in
  a debug build on a 64-bit box.

  The first is causing many buildbots to fail test runs, and there
  are multiple causes with seemingly no immediate prospects for
  repairing them.  See python-dev discussion.

  Note that a branch can (and should) be created for resolving these
  problems, like

  svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH

  _PySys_Init():  It's rarely a good idea to size a buffer to the

  11 for -(2**31-1)).  So reserve 128 bytes instead -- nothing is

  SF patch 1501987:  Remove randomness from test_exceptions,
  from ?iga Seilnacht (sorry about the name, but Firefox
  on my box can't display the first character of the name --
  the SF "Unix name" is zseil).

  This appears to cure the oddball intermittent leaks across
  runs when running test_exceptions under -R.  I'm not sure
  why, but I'm too sleepy to care ;-)

  The thrust of the SF patch was to remove randomness in the
  pickle protocol used.  I changed the patch to use
  range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
  cPickle, and randomly mucked with other test lines to put
  statements on their own lines.

  Not a bugfix candidate (this is fiddling new-in-2.5 code).

  * If BuildApplet.py is used as an applet it starts with a version of
    sys.exutable that isn't usuable on an #!-line. That results in generated

    sys.executable.

  documentation that exists for that unadvertised module.  (people
  really should really just use sqlite3)
