Don't reload the KConfig object of the standard addressbook for every
incidence during loading, by caching the "thatIsMe" entry. This should
speed up calendar loading significantly, but it means that if they user
changes their "thatIsMe" entry in the addressbook, KOrganizer won't
realize that until the next restart. Given the spectacularly low frequency
with which that is expected to happen, I think that's worth it. I can't
fix it at the root, since that is in kdelibs. Will try to fix it in
kdelibs 3.5, though, obviously. (proko2 issue 1118)
