I'll read up on that report to see if it provides some more clarity.

Did you reduce the usleep time? The code I sent uses the 100 ms wait 
time, in which case I don't see a problem either, but when I reduce that 
to 10 ms the issue pops up very very fast.

That's good to know. :) That would explain the warnings I got when 
uncommenting them then.


Kind regards,
