strxfrm doesn't work that way (and if it did, it would give back a
malloc'd not a palloc'd string).

No it won't; see the man page for strxfrm.
This does raise an interesting thought though: what platform are you on?
It seems to me that we've heard of buggy versions of strxfrm that write
more bytes than they're allowed to, thereby clobbering palloc's data
structures.
