  log: "Pull up following revision(s) (requested by sborrill in ticket #1643):\n\tsys/net/if.c:
    revision 1.243\nPrevent if_detach() from crashing while it walks the routing table\nto
    find and unlink routes that reference the detached ifnet: make\nif_rt_walktree()
    return ERESTART whenever it has deleted a route.\nWhenever rt_walktree() returns
    ERESTART, if_detach() restarts it.\nI believe that this fix resembles one by Jonathan
    Kollasch or by someone\nelse, which has languished in a PR for too long.  Sorry!\nTested
    by me and by Jeff Rizzo.\nXXX It's supposed to be safe for rn_walktree() to apply
    to the routing\nXXX table a routine that may delete routes.  Why isn't it safe
    in\nXXX practice?\n"
