Almost. Before that, please just rebase on the patch I attached in my 
previous message: I see you (re)introduced various problems, like '/' at 
the end of lines, instead of the beginning; size_type 
__saved_next_resize wrongly non-const in rehash(size_type); the comment:

  	// Allocate the new node before doing the rehash so that we don't
  	// do a rehash if the allocation throws.


again in the wrong place. There may be more, just rebase, please.

Paolo.
