I would go so far as to make this 60 seconds and or have it a configurable parameter.

Previously the timeout was infinite.   I have observed process creation lagging by 30-45 seconds on a server with a load average of +300.   The new bitbake python code with the reduced timeout is not yet running on our edge case testing environment, but I do expect to hit the same issue.
