Yeah, no-one else but the tests need this. I doubt anyone will call this
from a module and IIRC if it's not marked _X_EXPORT it won't be usable from
modules anyway. If you have a good idea on how to mark functions as "static
if it wasn't for a test", that'd be great.

"dix: allocate temporary grabs on the heap" does that. I ran this through
valgrind and it didn't complain, iirc.
