I do not think that this is a good solution: it is risky to make
web requests to ones own Zope instance.

To see the risk, assume for a moment that your allow just for a single
worker. Then http requests to itself will deadlock deterministically.

The risk is smaller for larger numbers of workers -- but never zero.
For two workers, assume that both start to execute requests that
later make the client call. Deadlock will be the result again.

Why does the Python script with proxy role not work (I did not understand
this)? It should!
