------------------------------------
In the way you suggest

{code}
case LOCALIZED: break;
case REQUEST:
+ if (rsrc != null && (!isResourcePresent(rsrc))) {
+ LOG.info("Resource " + rsrc.getLocalPath()
+ + " is missing, localizing it again");
+ localrsrc.remove(req);
+ rsrc = null;
+ }
.....
{code}

Once R1 had been localized, and the disk went bad, we would never again check
if it still exists. That's entirely the problem we are trying to solve here.
