fwd_ior threading race and patch

[Felipe Magno de Almeida]

Hello Karel,

We noticed a race with the fwd_ior member of Object when multiple
threads made calls concurrently. We've fixed it by moving the forward
object outside the reference and to the algorithms. The attached patch
has been working for over 1 year.

Any comments are appreciated,

Regards,

Hello Felipe,

thanks a lot for your patch, but before merging it into source tree I'd
like to duplicate the issue myself. By any chance do you have as simple
as possible example which duplicates this issue? I'm asking for it since
from the very quick look into the patch I don't see how it fixes the
issue exactly -- so I'd like to get it here on my "desk" and investigate
a little bit this...

Thanks a lot,
Karel

Hello Karel,

I probably won't be able to give you a sample, but Ricardo Cosme
probably can. What I can do right now is say that this bug appears
with constant throwing of ForwardRequest, which causes the
modification of the reference in the fwd_ior member variable.

I can fill in more details later.
