The deadlock Alan pointed out can happen also with single page allocation if we in 2.4.x-current put a loop in GFP_KERNEL.

You're right. That's why it's a waste to have so many order in the buddy allocator. Even more now that the hashtables should be allocated with the bootmem allocator! :) Chuck seen the slowdown of increasing the highest order allocation in his bench. But of course in 2.2.x we can't avoid that.
