BTW, withCString in my implementation which handles charsets does not
use alloca but malloc. It's because we don't know the length of the
resulting char[] until we convert it, so we cannot preallocate it.
We must guess an initial size and realloc the array as needed.

Hence unfortunately speeding up alloca won't speed my implementation
of the common need of allocating C objects.
