    Cygwin: /proc: don't exit prematurely from /proc/PID/status
    
    If a process is just exiting, requesting memory info may fail
    with STATUS_PROCESS_IS_TERMINATING.  Right now the code just bails
    out if fetching mem info fails.  However, the rest of the info is
    still valuable for procps, so just carry on.
