This wasn't exactly what I anticipated. It intended that it should report
the error *and* return as an error to the caller, rather than carrying on.

That said, I notice that none of the existing code we have committed for
VirtualBox driver deals with OOM on strdup() calls, so this patch is not
making things any worse. Thus I think we can commit these patches and
fix all the strdup calls in one go, later.
