I will quote what Hongyan wrote back on the first report:

The best solution is to make the heap scalable instead of a global
lock, but that is not going to be trivial.
Of course, another solution is to keep the domctl lock dropped in
domain_kill() but have another domain_kill lock so that competing
domain_kill()s will try to take that lock and back off with hypercall
continuation. But this is kind of hacky (we introduce a lock to reduce
spinlock contention elsewhere), which is probably not a solution but a
workaround.

Interesting. Is contention on the heap lock merely suspected or
was that lock proven to be the problem one?
