I think I will use this solution.
I have just had a go at implementing something like that, but failed to
find the right way to do it. May be what I want to do is not possible:
Currently, the 'new-buffer' signal is emitted by a ArvStream object,
which leads to the thread join issue I have described. What I would
like to do is to define a signal in ArvStream, but with a signal
callback that doesn't have ArvStream as the first parameter, but an
ArvBuffer. Do the signal callbacks always have the object emiting
instance in their parameters ?
Cheers,
Emmanuel.
