It does, though with a very low frequency: $ ./unlinktest $ ./unlinktest 10000 read 0 bytes, unexpected $ ./unlinktest 10000 read 0 bytes, unexpected read 0 bytes, unexpected $ ./unlinktest 10000 $ The failure rate on my recent-vintage laptop is more like one failure every five loops. regards, tom lane
