Cool idea.  I may mention it in the PEP as a possibility.  Thanks!
That is not so cool if for some reason an application routinely loads
and unloads modules.


Do applications do that for some reason?  Python module reloading is already so marginal, I thought hardly anybody did it.

Anyway, my admittedly-dim understanding is that COW is most helpful for the "pre-fork" server model, and I bet those folks never bother to unload modules.
