Repeated calls to sched_setaffinity slow down rendering

I have a program that performs off-screen rendering of a simple scene repeatedly, as fast as possible.
When I run it, I get 450 fps. Looking at a CPU profiler, I noticed that the sched_setaffinity system call was taking a lot of time.

When I comment out this line, I get 600 fps on the same benchmark:

filament/libs/utils/src/JobSystem.cpp

Line 442 in 05ce5ea

setThreadAffinityById(state->id);

Given the comments, it sounds like this is working around an Android issue. Would it be possible to make this build-configurable, to avoid paying this cost on other linux platforms?
