Does this simple recipe need lockfiles?

Hi!  This recipe does what I want it to (save a copy of the header of
non-mailinglist mail to the file ".my_mail", and a copy of the whole 
message to the file "mysave":

:0 c
* !^FROM_DAEMON
{
  :0 hc
  .my_mail
  :0
  mysave
}

But I'm unsure if a lockfile (or lockfiles) are advisable.  The procmailex
man page gives examples that don't use them, but gives very similar
examples in which they *are* used.  I'd very much appreciate any advice.

Thanks!
