This is problematic, there are too many decorators to patch already and I
think there are also non-decorator side-effect patterns used in the wild.
The Python language is too free and developers can easily write code with
all kinds of side-effects. We will never be confident enough: we cannot
devel-warn them. And I can imagine developers yell at chg.
Just an example, I think this is a legit:
from hgext import histedit
Patching histedit.action is a bit too much and does not worth it imo.
Therefore, I think the cost of possible multiple server processes is very
worth to eliminate the uncontrollable side-effect issue. For common users,
there is usually only one server process.
