John Spence asked,

Doesn't that manually-administered list rewrite the From_ line at least?
That's virtually indispensable.

Three major reasons for not using a local lockfile:
1. the recipe saves to a directory rather than to a plain folder; or
2. the recipe's action does not modify any files (it opens a brace nest,
for example, or it does filtering or variable capture, or it dumps
the message to /dev/null), so it is safe for it to operate on two or
more messages at the same time; or
3. a global or regional lockfile is in effect at that point.
