With Python 2.5.2 and 2.6.0 all tests are passing with any error. With 
Python 2.4.5 seven tests are failing because 2.4 doesn't support mmap 
with a negative file number.

File ".../python-multiprocessing/Lib/multiprocessing/heap.py", line 56, 
in __init__
     self.buffer = mmap.mmap(-1, size)
EnvironmentError: [Errno 9] Bad file descriptor
