Indeed, it turns out that I only disabled the "harvest all emails from 
nepomuk" code (AddresseeLineEdit::Private::startNepomukSearch) but not the 
"akonadi contact search job", which itself uses nepomuk (!)

We discussed it further in #kontact today, and apart from nepomuk being able 
to run queries in parallel, we also need akonadi to not wait for that 
ContactSearchJob anymore. Which seems to require:
1) running these jobs in a different akonadi session, and
2) making it possible to actually kill these jobs, when typing something 
different and especially when sending the mail (no completion needed anymore).

Volker volunteered to make these changes (well, technically only the lower-
level part of point 2, but I'm writing this email so I can say whatever I want 
:)

However, thinking about it again, wouldn't it be enough for now to just do the 
first point? At least completion wouldn't block sending, it would only block 
further completion in the next composer (assuming this is a shared session).
If it's a new session in every AddresseeLineEdit (assuming akonadiserver is ok 
with 10 of these in parallel), then this isn't even an issue.
