Hi Andreas,

This is strange because the only caching I can see for  is the "in request"
caching in the plone_context_state. I made a portal_tab action in a vanilla
Plone 4.1 with this condition (and no permission) :

python:portal.plone_log('evaluating', 'a portal tab') or True

A new line appears in the log for each user request, no more, no less.
Perhaps are you using a 3rd party component that makes a more aggressive
cache on portal_tabs.
