No.  I am still rather frustrated that was the problem.

The only reason I feel safe with this solution is that the file
pointer is not directly used except by _fileio to get the file
descriptor.  I would not trust this if the file pointer and file
descriptor had intertwined uses.  But I would trust rewind() if the
file pointer is used the entire time.

Thanks.  I just wish this whole ordeal had not been necessary (filed a
bug report with Apple in hopes that this can be prevented for someone
else).  I can see why some people prefer to hack on PyPy, IronPython,
or Jython instead of dealing with the joys of C.  =)
