Okay, I have updated the packages (same location:
https://www.hamishmb.com/files/cygwin-temp/). It should now handle fork
errors better.

If it fails again, please post the full output from the test command so
I can see what version(s) of Python the tests are failing on. It might
be useful for someone else to have a go as well - would be good to know
multiple people can reproduce this issue as I have still had no luck
doing that.

Thanks for your patience,

Hamish
