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

[Anthony Molinaro]

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
