This is dead code and there is probably no good use for it.
This is simple daemon which peridically opens files (defined in /etc/polld). I use this for scanning partitions in card reader, which does not report card insertion/removal. With polld, they appear in 10 seconds after insertion and udev will then create appripriate device nodes.
