+pppd: Close already open ppp descriptors
+
+When using the kernel PPPoE driver in conjunction with the "persist" option,
+the already open descriptor to /dev/ppp is not closed when the link is
+reestablished. This eventually leads to high CPU load because the stray
+descriptors are always reported as ready by select().
+
+This patch closes the descriptor if it is already open when establishing a
+new connection. It originated from the Debian project.
