Looks good here.

I reproduced fairly quickly with RT host and 1 RT guest by just having
the guest do a parallel kbuild over NFS (the guest had to be restored
afterward, was corrupted).  I'm currently flogging 2 guests as well as
the host, whimper free.  I'll let the lot broil for while longer, but
at this point, smoke/flame appearance seems comfortingly unlikely.
