So, why does Xen call domain_destroy() on domA?  I but a BUG_ON(1) in
domain_destroy(), and lo, the console produced the output below.  My
guess is that domA is destroyed via some callback waiting for its
zombified mapping to be released.

Ah, I think I see the problem. Can you please try switching the order of the calls to domain_relinquish_resources() and gnttab_release_mappings() in common/domain.c:domain_kill()? i.e., the new order should be:

I think that should fix the crash.
