It seems to be handled by competent people on the redhat bugzilla
(Siddhesh Poyarekar in particular). So unless someone wants to
help them or to dig into the problem himself, I think we should wait
for the outcome they will find. They will probably push the fix
upstream anyway.
  I initially opened the bug because I was thinking that the bug
would be a regression in the Debian experimental version. But, I was
surprised to find the bug also in the Debian stable version.
I still report it so that we (in Debian) know the bug exists and is
being working on (in case some people look at the BTS when they
see a deadlock).
  If the fix is not too intrusive, perhaps it will be possible to
patch the Debian stable version.

  Regards,
    Vincent
