Hmpf... it seems that the problem was in setting the trigger to any instead of read. Once I set it to read, everything works like charm.

Sorry, I didn't have time to look into this, yet. But this is
interesting - if anything, I would expect any to trigger more often
than read, but not the other way around. I'll review that part of the
code when I get some time.
