Hi Halley,

And I also don't what "1" is valid return value from the write() function.
good catch. It is our fault and actually a stupid oversight on our side.We have to do this writing 1 byte into the pipe to wakeup the clients.So writing one byte successfully doesn't give us 0. It gives us 1 and sothere you got your wrong value.
I fixed this in the CVS now. Thanks for the analysis.
