Summary: tarfile violates bufsize

Initial Comment:
tf = tarfile.open(mode = 'w|gz', fileobj=fileName, 
bufsize=20*512)


The following text says how many bytes tarfile writes to 
the 'fileName.write' function. Notice that when closing 
the tarfile it writes way to many bytes!  This happes 
just sometimes. Some directories might work, other 
might not.


...
write len: 10240
write len: 10240
Closing archive
write len: 24815  # Somthing is wrong?
write len: 4
write len: 4

I've committed my fix as rev. 1.10 of tarfile.py.

The close() method just writes the contents of self.buf to the file without 
breaking it up into blocks.  

Please try the attached patch and let us know if it fixes the problem.
