     [monitor.c monitor_wrap.c session.h servconf.c servconf.h session.c]
     [sshd_config sshd_config.5]
     Make the maximum number of sessions run-time controllable via
     a sshd_config MaxSessions knob. This is useful for disabling
     login/shell/subsystem access while leaving port-forwarding working
     (MaxSessions 0), disabling connection multiplexing (MaxSessions 1) or
     simply increasing the number of allows multiplexed sessions.
     Because some bozos are sure to configure MaxSessions in excess of the
     number of available file descriptors in sshd (which, at peak, might be
     as many as 9*MaxSessions), audit sshd to ensure that it doesn't leak fds
     on error paths, and make it fail gracefully on out-of-fd conditions -
     sending channel errors instead of than exiting with fatal().
