-------------------------------

commit 87d7230171ec7a3ad2d232fbffc5bfc94f9cd68c
Author: Greg Mann <greg@mesosphere.io>

    Fixed an FD leak in the IO switchboard.

    Previously, the IO switchboard could leak file descriptors
    because it held a reference to its server socket within the
    socket's accept loop. This patch explicitly discards the
    future containing this reference to eliminate the leak.
