Doing hg backout does not apply cleanly for me.

There is a conflict in globals.hpp. But the patch file provided in the 

applies cleanly for me and does the right thing to globals.hpp.

Will you push the fix for "Rename and clean up the ParGCAllocBuffer 
class" with the correct bug number at the same time? Would be nice to 
minimize the window where the repo is in an intermediate state.
