I did not mean more bitmaps but more elements per bitmap, obviously.
I know the effect of the patch, or I wouldn't have written it  ;-)

I tried to add something like df_hack2 to the reaching defs problem,
but I didn't succeed the first time.  It is indeed harder.  If you
could work in it, that would be terrific.

I will work on some tools to investigate DF memory usage.
