  Modified files:
    usr.bin/tail         forward.c 
  Log:
  If the kevent() registration fails (probably due to the underlying
  filesystem not being kq-aware), then fall back to using sleep.  This
  allows tail to work with NFS filesystems again without chewing up CPU time.
  
  When given the -F flag, resort to sleep/stat after the file was moved
  or deleted.  This allows a window where the file being tailed does not
  exist at all, which is typically the case during log rotation.  Switch
  back to using kq (if possible) after the file is reopened.
