? maybe i'm just misreading the source:

[mingo@hal linux]$ grep __GFP_WAIT *.h
mm.h:#define __GFP_WAIT 0x01
mm.h:#define GFP_BUFFER (__GFP_LOW | __GFP_WAIT)
mm.h:#define GFP_USER (__GFP_LOW | __GFP_WAIT | __GFP_IO)
mm.h:#define GFP_KERNEL (__GFP_LOW | __GFP_WAIT | __GFP_IO)
mm.h:#define GFP_NFS (__GFP_MED | __GFP_WAIT | __GFP_IO)
in all these cases we wait definitely for the first swapout(s) to finish
...

-- mingo
