TBH I've suspected problems with misuse of the bias for attach/detach before,
but I've not come up with a test case. I'll have a look.
Thanks!

FWIW, I don't think we should do this implicit unmapping, particularly since it
implies an expensive device-to-host-address lookup.

For strictly-paired acc_map_data/acc_unmap_data calls that don't interfere with
