The problem with that is that we really want to have multiple
"last-resort" pools.

For example, NFS would probably also be happier with a last-resort pool
for kmallocs (of both 8kB and 16kB allocations - we don' tneed a very deep
pool, just 2-4 allocations would probably be fine to handle the bad
cases), but we do _not_ want to allow NFS starvation to starve fork()'s or
vice versa.

I certainly agree with making this a more generic thing, but it mustn't be
just a flag that everybody then fights over.
