that's not about whether or not it can works. I think it's just confusing to
clone and share a context in a mono thread where the only thing you want out of
it, is a xenstore handle. You can simply clone a new xs handle, and worst case
scenario, you can extends the xl context to store 2 xs connections.
In the end, the approch is overkill, and complex solution often lead to
unforseen bug (at this was the case here)

definitely not worried about that. libxenlight is not a library where
performance matters. (not that i'm saying it will be slow either)
