So in the new (soon-to-be 3.4) heap API, are

alloc_domheap_pages(NULL,order,flags)

and

alloc_xenheap_pages(order,flags)

synonomous on 64-bit hypervisors?  I.e. they
are allocating from the same pool of pages?
And if so are the matching free routines
synonomous?

If not, under what circumstances should one be
used rather than the other?

Are there any cases now where free_XXXheap_pages
might free up pages that could be grabbed by
another domain and those pages have not been
scrubbed?

Thanks,
Dan
