A variant of this software design approach can work also for my data processing
needs to some degree.
Command example:
elfring@Sonne:~/Projekte/Linux/next-patched> time spatch --timeout 9 -D
database_URL=postgresql+psycopg2:///serial_DVB_duplicates --dir
drivers/media/dvb-frontends --sp-file
~/Projekte/Coccinelle/janitor/list_duplicate_statement_pairs_from_if_branches8.cocci
>
~/Projekte/Bau/Linux/scripts/Coccinelle/duplicates1/next/20190418/pair-PG-serial-DVB-results.txt
2>
~/Projekte/Bau/Linux/scripts/Coccinelle/duplicates1/next/20190418/pair-PG-serial-DVB-errors.txt
real 1m54,399s
user 1m52,667s
sys 0m0,382s
Such a data analysis produces an usable result if it is performed
by a single process.
The applied software combination “Coccinelle 1.0.7-00186-g99e081e9 (OCaml
4.07.1)”
supports also parallel data processing by using background processes.
I observed that no data were imported then into a specified database table.

The main developer for the semantic patch language does not like
to debug anything that involves external tools (including my application
of your class library) at the moment.

So I am looking for additional solution ideas from other information sources.
Where would the desired data get lost on the transmission to the database table
during usage of background process?
