Jerone,

Did you not see Jim Dykman's updates and posts on this bug?
He's found the root cause, and is putting together a patch,
although some of it might be interim because it exposes
another resource shortage which will have to be addressed
somehow. Expect a patch from him in the next day or two,
and see the bugzilla entry (and previous posts on xen-devel)
from Jim for the details.

thanks,
Nivedita
