<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The tricky part is that filterAcceptsRow() must not use the cache
(too bad, it would be faster), because of the setFilterFixedString()
feature which can change the filtering status of indexes without
KRFPM even being informed (QSFPM has no virtual method, no event...)
So it only ever writes to the cache, but when dataChanged()
or row insertion/removal comes in, we can look into the cache
to find the old state and compare.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Using kmail (and especially testing the substring filtering in the "move dialog", which an earlier version of this patch broke).
Looking at the number of calls to Akonadi::FavoriteCollectionsModel::Private::reload() for a single dataChanged() signal from the ETM, which went from 10 to 4 (still too many, but the remaining problem is elsewhere).</p></pre>
