[New-bugs-announce] [issue7571] Change 'name' of Process - assertion failure if Unicode

New submission from Frank Millman <frank at chagford.com>:

At the top of my program, I have 'from __future__ import 

I subclassed Process, and passed "name='test'" as an argument. I got 
the following traceback.

Traceback (most recent call last):
  File "F:\junk\multiprocess\mp5.py", line 37, in <module>
    p = Frank(name='test')
  File "F:\junk\multiprocess\mp5.py", line 18, in __init__
    self.name = name
  File "C:\Python26\lib\multiprocessing\process.py", line 141, in name
    assert isinstance(name, str), 'name must be a string'
AssertionError: name must be a string

If I change the argument to "name=str('test')" there is no error.

For Python 2.x I think the assertion should be "isinstance(name, 
basestring)" to prevent this from happening.
