  How does that systemd thing clean tmp dirs at runtime, IOW, how can it know it's safe to clean up a given file if the application that created it doesn't do something explicit to guarantee cleanup?
  
  I'm not aware of anything like this for Mac (besides a reboot) or MSWin ...

  How could this be a race condition?

  I'd be fine with that if libclang never left its big pch files behind even on a clean exit. The argument that disk space is cheap doesn't really fly here because users can make certain that tmp dirs which will hold performance-critical files end up in places with stricter restrictions, like a ram disk.
  They could of course do what my patch does in a wrapper script ... but they could also just use vi and make for software development ;)
