Re: [PATCH] Hot/cold partitioning fixes

[Caroline Tice <ctice at apple dot com>]

I'm working on a patch to fix PR 20719, which should also take care of 
this problem.
It includes David Edelsohn's earlier patch as well, with some slight 
modifications.  I'm
hoping to have the problem fixed and the patch ready for submission 
later today.
