True for the read cache, not so true for the write cache.

For example there could be data that has not yet been written to its backend. 
That would be the case if Akonadi is shut down (e.g. due to logout) while one 
of the resources that had user changes was not online (e.g. could not connect 
to its server).

There could also be meta data that a backend was not able to handle itself, 
e.g. read/unread status of emails from an mbox file.

While discarding of meta data would be no more than an annoyance, discarding 
of uncommitted changes could be (an uncommitted deleted would be just an 
annoyance and uncommitted add not so much).

Cheers,
Kevin
