Yes, I do that as well. Thank you for pointing that out.

But my application requires that all transfers should occur within a fixed
time period. I don't really care whether they are complete or not, I just
want to breakout after say 100ms irrespective of whether all transfers are
done or still incomplete. In that case, am I doing the right thing or not?
