 Been doing a binary search to find at
least one of the things causing a crash.   What I have now is that
the following call from libOS reliably crashes xen.
 
 the call is:
          
      rc = hcall_read(ret, flags, idx + i);
 In the library OS , with parameters:
 flags - 0, idx = 0 ret = 240948
 
 That coems into xen as hcall "c"
with the following registers:
 (XEN) sync_vcpu_execstate: called
 
 (XEN) <hcall c>----[ Xen-3.0-unstable
    ]----
