Note that we had a problem related to this with a client recently: In CMF, skin data is stored in portal._v_skindata, and is actually needed for the whole request, but in some ZEO setting this go cleared by a get_transaction().commit(1) which was unexpected and led to breakage because in that batch treatment we used some skin methods too... We ended up calling portal.setupCurrentSkin() after the commit() to reset the skins. FYI.
