Please don't reply privately. Having done so, instead of replying to the
mailing list, made both mails into the spam filter, and so I didn't see
them; also no one other than me could try to help you.

Anyway, if you guess that LibreOffice can ever be run completely
single-threaded, you are mistaken. It creates threads always; it need
multiple threads, and there's no "single-threaded LibreOffice". What I
suggested was not about making everything in LO to be single-threaded,
but only (re-)calculation of a spreadsheet.

You need to tell where - at which stage - are you now, and what is your
end goal (what you try to debug). Likely you need some code reading; and
yes, LibreOffice is not a simple reading. Possibly I (or others, if you
follow the rules of using mailing lists) could advise where to put the
breakpoint in order to break into it, whichever thread could that be.
