I don’t see an easy way to avoid doing that initialization here; it might be possible by adding more lazy-init logic to only look up the min and max scheduling priorities when they are actually needed, but I suspect that would still be before the end of the initialization code. > > Hence not something we should try to fix IMHO. Agreed. What Till describes seems a clear bug with some wrapper which matlab is injecting (maybe with LD_PRELOAD as well).
