    Prefix pselect functions to clarify debug messages

commit 10e45654cff221ca60fd35ee069df67208fcf415
Author: Darren Tucker <dtucker at dtucker.net>
Date:   Fri Aug 20 08:30:42 2021 +1000

    Fix race in pselect replacement code.
    
    On the second and subsequent calls to pselect the notify_pipe was not
    added to the select readset, opening up a race that om G. Christensen
    discovered on multiprocessor Solaris <=9 systems.
    
    Also reinitialize notify_pipe if the pid changes.  This will prevent a
    parent and child from using the same FD, although this is not an issue
    in the current structure it might be in future.
