-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.
