Is it OK to check it in, Vladimir?  The patch would go in unchanged:

Regression re-tested now on {x86_64,i686}-fedora-linux-gnu.

The `floating' lockup will get fixed by a later patch using this new
all_root_varobjs function.   A testcase for it was in a now-obsolete patch:
	[patch] Fix gdb.mi hang on floating VAROBJs
	http://sourceware.org/ml/gdb-patches/2009-05/msg00433.html
This patch itself still does not fix it.

The (small) memory caused by the current semantics you fixed by:
