Yes indeed, I didn't notice. Sorry for the dupe.

I looked at the thread of last July. One of your proposals is to just
keep the connection lock when doing the callbacks, with the
restriction that no dbus function using the connection can be called
in the user code, or it would deadlock. I guess we could even get rid
this restriction if the connection lock is made reentrant, but that
would be risky I guess. I tried to just keep the lock and it does
solve my problem, but it might break other bindings.
So which solution among those detailed in the earlier thread would you
recommend ? (that is, which one can I write a patch for ? ;)

Best,

Olivier
