  I'm discomforted of possibility that I'll download in-buffer for not-so-easily-accessed 
computer 'R' with blocks at subspace 'A', and next day (next week) reassigment in 'A' 
will begun. And when I'll manage to take out-buffer from 'R' (2-4 weeks later) those 
keys will aready be scanned by someone else.
  I'd just like to hear that this possibility is impossible.
  Or - that it's a real scenario ;-( - then I'd better switch to OGR or MP or some other "idle 
client" on those computers, when current key subspace will be almoust exhausted.
