93 * Number of extension functions which we can dynamically add at runtime.
95 * Number of extension functions is also subject to the size of backing exec
96 * mem we allocate. For the common case of dispatch stubs with size 16 bytes,
97 * the two limits will be hit simultaneously. For larger dispatch function
98 * sizes, MAX_EXTENSION_FUNCS is effectively reduced.
