r24282: Try to fix the occasional Samba4 crash in BASE-BENCH-READWRITE, as
seen in particular on opi. This looked like a Heimdal problem, but I think it was simply that we didn't do a talloc_reference() to keep tabs on the memory we were using, and in between obtaining the pointer and using it, it was assigned to unrelated memory.
