Yes, you *can* loop CRM114 forever, or spawn single-shot demons.

Both techniques are documented in the big manual.  Especially see
the "Beast with a Thousand Young" test, where it turns out that
we can spawn with only milliseconds of overhead (and write-append
to files fast enough that the file system itself loses bytes).

Not quite.  There's one bug in the script I gave you (I realized it
this morning walking in to work), and one typo.

The typo is easy: it plucks out the alt and img, it should pluck
out alt and title, so change:

     match <nocase> [:whole_img_tag:] /img=[[:graph:]]*/ (:img_txt:)
to
     match <nocase> [:whole_img_tag:] /title=[[:graph:]]*/ (:img_txt:)

The bug is also easy to fix.  The ISOLATE statement in the second
stanza (the one dealing with IMG tags and which plucks out
only the "title" and "alt" fields) actually needs to be split
into two so both will initialize to NULL strings;  change:

   isolate (:img_txt: :alt_txt:)

to

   isolate (:img_txt:) //
   isolate (:alt_txt:) //

and that might even be all you need to do.

There are some optimizations you can also do, but those are 
unnecessary for now.  (they are to use "fromend" flags to 
skip over the already processed text for each pass.
