More kqueue work on master

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

    A couple more fixes to poll/select/kqueue have been pushed to master
    as part of the recent kqueue work.   In particular this latest push
    will fix mountd which was getting stuck in a Run state, and may fix
    other stuck socket issues.
