Re: [libvirt] [PATCH] Avoid use-after-free on streams, due to message callbacks

When sending outbound stream RPC messages, a callback is
used to re-enable stream data transmission. If the stream
aborts while one of these messages is outstanding, the
stream may have been free'd by the time it is invoked. This
results in a use-after-free error
