Well, it would be possible that it stopped indexing but is still processing an 
item from before. I cannot instantly freeze the indexing process, I can just 
stop throwing more stuff at nepomuk (so stopping may take a couple of seconds, 
or 60s to be on the safe side).

So you're saying there is no query running and virtuoso is constantly running 
full throttle? In this case that's something for the nepomuk folks.

In this case it's not the indexer. The email indexing option controls the 
whole akonadi_nepomuk indexer. If it's off it's not related to the 
akonadi_nepomuk_feeder and clearly another problem.
