[erlang-questions] Re: Possible leak in inets httpc.

Hi, anyone know if its safe to backport this fix to R13B04?  I'm in the process
of deploying R13B04 as an upgrade from R12B05 and since I make heavy use of
httpc this will bite me.  Ideally, I can just grab the appropriate files from
git and plop them into my R13B04 when I build an rpm (of course I need to
remember enough git to do that :) ), so wondering if it's possible or if
there are deps outside of the inets directory which matter?

Thanks,

-Anthony
