I think Jeff correctly assessed the situation. Between the
time the tasklet leaves select() and performs the channel
operation, the state of the channels could change. This
would most likely mean
1) The selected channel when unblocked, was placed at the end of the
runnable list, allowing other tasklets to change the state of the
selected channel.
2) Between select() and a channel operation, the tasklet in question
did something to cause a context switch and allow another tasklet to
change the state of the selected channel.
Cheers,
Andrew
