If the argument to pool.map (f, args)
is
f = functional.partial (my_func, some_keyword_arg=whatever)
I get:
Traceback (most recent call last):
File "/usr/lib/python2.5/site-packages/multiprocessing-2.6.1.1-py2.5-linux-
self.run()
File "/usr/lib/python2.5/site-packages/multiprocessing-2.6.1.1-py2.5-linux-
