On MacOS, I am having trouble and need MAKE_JOBS_SAFE=no, because when built in parallel some files seem not yet built when another rule tries to do something with them.  I’m wondering if this is a platform-specific problem or a more general one.

Mine has 8 and I was running with MAKE_JOBS=8.  

I think sometimes it worked and sometimes not, but I was not paying systematic attention to that.
