Opinions please -- how big should a single module grow?

[Steven D'Aprano]

This is a style question rather than a programming question.

How large (how many KB, lines, classes, whatever unit of code you like to 
measure in) should a module grow before I should break it up into a 
package? I see that, for example, decimal.py is > 3000 lines of code, so 
I can assume that 3 KLOC is acceptable. Presumably 3000 KLOC is not. 
Where do you draw the line?

For the purposes of the discussion, you should consider that the code in 
the module really does belong together, and that splitting it into sub-
modules would mean arbitrarily separating code into separate files.
