This sounds like bugzilla #183. gnttab_end_foreign_transfer() finds 
shared[ref].flags is GTF_accept_transfer and happily returns a null
frame, which is then happily mapped. When it is dereferenced, you crash.
If I change gnttab_end_foreign_transfer to wait for the grant, it never
seems to complete properly. I'm still working on

I'm on FC3; nics=2 is enough. It fails on the first packet AFTER the 
second interface receives its first packet.
