Reviewed by Justin Michaud and Mark Lam.
This fixes some behavior with Wasm tests where executable allocation
fuzzing leads to Wasm modules exiting early due to a pretend failing
allocation. These thunks aren't very large, and we shouldn't fail to
allocate these unless the entire system is OOM anyway.
