This could be made *much* easier with #10785, which has been waiting for a review for 9 months now :-p

To catch the release manager's attention, you need to set it to positive review, IIRC.

That's totally wrong, I'm told one needs to sing and dance around a fire until the Release Manager comes :-)

and put the milestone to sage-duplicate/invalid/wontfix please, so I know there is nothing to be done besides closing this ticket.

Already found the parameter its:
int CPX_PARAM_THREADS = 1067
PXsetintparam(....,CPX_PARAM_THREADS, #Params);
We could add a parameter to MixedIntegerLinearProgram?(..., solver_parameter=Params(#Threads...)...)?
