Since libc++ seems to allocate, could we sanity test that?
```
// The test below is non-portable because it expects `std::thread` to call
`new`, which may not be the case for all implementations.
LIBCPP_ASSERT(numAllocs > 0); // libc++ should call new. Sanity check
`numAllocs`.
if (numAllocs > 0) { ... }
```
