Different situation; a nesting block that does not launch a clone cannot

the `w' or `W' flag to the recipe that creates the clone (I've never dared
to try it without `w'), but that may be unnecessary.
I tried it without the "w" and I ended up in a dead-lock situation and I
had to manually remove the lockfile.
Basically, in my .procmailrc I have:
"file" must not be modified while in here
append something to "file"
Can someone explain why the "w" is important -- and what exactly it is
