Ok patch combination final score for me is as follows in the presence of a 
large continuous write:
1 No change
2 No change
3 improvement++; minor hangs with reads
1+2 improvement+++; minor pauses with switching applications
1+2+3 improvement++++; no pauses

Applications may start up slowly that's fine. The mouse cursor keeps spinning 
and responding at all times though with 1+2+3 which it hasn't done in 2.4 for 
a year or so.
