   call check_pipe from write_or_die here instead of

Yes, might be better. I wasn't sure because the check_pipe is
not public.

Where would you declare check_pipe? In cache.h?

IIRC, once upon a time the community decided to not
clutter cache.h any more as it is like a dirty kitchen sink,
piling up all unrelated things, but on the other hand that
would be handy.

Maybe it would be more suitable to move check_pipe to
run-command.h/c?

That's certainly possible.
I don't have a strong opinion, where the code actually
resides, but I do have a strong-ish opinion on code
duplication. ;)
