Sorry, I had to quickly downgrade, dovecot ate more than 100k 
descriptors in some minutes... I just thought that there weren't too 
many changes between 4 and 5 and it's trivial from a diff where those 
descriptors can leak (maybe the pop optimization, that's what really 
spins here).
Of course I will look after it in a more quiet time.

I was worried about it too, but so far it seems to handle the load 
nicely. BTW, it would be nice to have some basic or advanced statistics 
about service times, it would be great to monitor that, and would also 
help to size those settings in a real system (finding the balance 
between in-process parallelism and the number of worker processes).
