Significantly better than the new IO based choking in 2.5.41.

mem_load:

2.4.19 [3]              100.0   72      33      3       1.49

2.5.41-mm1 [3]          144.6   50      37      2       2.15

Subtle differences only between 2.5.40-mm2 and 2.5.41-mm1 except for mem_load
which shows some relaxing of the aggressive swap avoiding in 2.5.40-mm2, but
still significantly longer than 2.5.41.

2.5.41-mm1 [3]          106.8   70      5       3       1.59

Slight drop off here, with longer kernel compile time despite doing less load work.
