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

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.
