BOINC Manager doesn't always keep the CPUS occupied

[original-birdman]

Describe the problem

I have systems configured to let BOINC use 3 CPUs.
I also have projects whose jobs run using multiple threads. I set these to run on 2 threads.

If the only pending jobs are all from this "threaded" project the only 1 of these will run and I end up with one unused CPU.
Because the total "pending time" of these 2 CPU jobs is more than pending additional work limit, no other project's job are downloaded, which could use that unused CPU.

Describe the solution you'd like

An option to download jobs from projects with no downloaded jobs if there are "spare" CPUs available but no current jobs can scheduled as they required more threads.

Additional context

This would be good, but it would require extending the client/server protocol
to let the request say "only send jobs that use <=N CPUs".
It's been a while since any project upgraded its server software.
