SubjectRe: [PATCH] mm: terminate shrink_slab loop if signal is pending

Digging some more into this I realize my last statement might be
incorrect. Throttling in this situation might not help with the signal
handling delay because of the logic in __alloc_pages_slowpath. I'll
have to experiment with this first, please disregard that last
statement for now.
