Once the last signalfd file descriptor for a given signal is closed - in our 
case, that's only one of them - shouldn't the handling revert to the default 
for that signal? Isn't it wrong that, when there are no signalfd file 
descriptors open for a given signal, the signal still seems to stay pending 
within the signalfd mechanism?
