Sure, it's used internally by glibc. But see the commit I made to
gnumach: that makes gnumach return an error. glibc thus doesn't actually
wait, just spinlock, i.e. behave correctly, just not so efficiently.

I see... so there must be fallback code (option 2 on my list); I just haven't found it.

Where is KERN_FAILURE handled in user space?
