multiprocessing Pool.imap broken?

[Yang Zhang]

I've tried both the multiprocessing included in the python2.6 Ubuntu
package (__version__ says 0.70a1) and the latest from PyPI (2.6.2.1).
In both cases I don't know how to use imap correctly - it causes the
entire interpreter to stop responding to ctrl-C's.  Any hints?  Thanks
in advance.
