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 (map works fine though). pdb shows `next()` is hanging on the condition variable `wait()` call in `IMapIterator`, so nobody is waking us up. Any hints? Thanks
in advance.

```
$ cat /tmp/go3.py
import multiprocessing as mp
print mp.Pool(1).map(abs, range(3))
print list(mp.Pool(1).imap(abs, range(3)))

$ python /tmp/go3.py
[0, 1, 2]
^C^C^C^C^C^\Quit
