One problem is that in 1.4.1SE the number of threads is still hardcoded.
If you want to I can give you a small patch that makes it a UCI option.
Other Toga variants have this already.
Yes I would like to include this patch. Are you the author? If I include it, I
would have to know the author for the copyright.
The variety of people in the chess engine community, that work on toga2 do
cause some sort of a "problem" for the debian legal policy.
Many thanks,

Hi Oliver,
Attached is the patch that makes the number of threads a UCI option.
I guess I am the author but the patch is really trivial.
Regards,
Michel
