New submission from cipater <[email protected]>:
I'm running 2.6.6rc1 64 bit on Windows 7
I get the following error when I try to instantiate a Pool:
>>> import multiprocessing
>>> p = Pool(processes = 2)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "c:\Python26\lib\multiprocessing\__init__.py", line 227, in Pool
