Hi Stuart,
I didn't explain my idea clearly enough, sorry (and I'm not in front
of a machine where I could just make a patch). Let me try again.
The idea is that callout ids are co{recursive_id}_n_m where n is of
course the callout list number and m the member of that list (as now).
Top level asciidoc is called without the user setting {recursive_id}
and it should default to ""
A recursive asciidoc is called with -a recursive_id="{recursive_id}_r"
where r is the count of how many recursive calls *this* asciidoc has
made.
Thats all there is to it, no tricky passing stuff up/sideways or anything else.
So for a three level two wide tree of calls {recursive_id} takes the
values (listed depth first):
"" for the top level
"_1" for the first child
"_1_1" for the first grandchild via child1
"_1_2" for the second grandchild via child1
"_2" for the second child
"_2_1" for the first grandchild via child2
"_2_2" for the second grandchild via child2

Then I can't build my documentation with make -j (ie multiple parallel
jobs) unless the "global" is very tricky and concurrent safe :(

Possible but UUIDs tend to be big and messy things.

Not all systems guarantee *not* to re-use PIDs after the processes
that have them exit, although Linux just keeps incrementing the PID.
But POSIX only requires that a fork return a PID that is not in use at
the moment, so successive children may have the same PID, been there,
fallen in that hole :)
