Change Details

This can be used instead of malloc_domain(M_WAITOK) in situations where we'd prefer to just fall back to an alternate domain if the preferred domain is depleted.

This ensures that malloc_domain(M_WAITOK) won't hang forever if one domain is depleted (e.g., because most of its memory has been wired by the ARC).
