Dom0 starvs DomU

[tg%gmplib.org@localhost (Torbjörn Granlund)]

I'm running NetBSD 7.0 with Xen 4.5, but in my experience this is true
for any NetBSD version using any Xen version from pkgsrc

When compiling in Dom0 (say, a new xentools version) all DomU's
essentially freeze.  I think DomU's which do not touch disk keep
running, but guest disk operations seem completely starved by CPU use in
Dom0.

I suppose this behaviour is well-known.  Are there plans of fixing it.

It is worth noticing that Linux+Xen does not show the same problem.
