Every one of these is locking the same mutex.  You could make arrays outside of the async work that is `num_compile_units` entries, and put each result in its own entry in the array.

After the wait, you could make more async workers.  One for each variable.  like `m_function_base_name_index.Append` could be one async job, and the same for each of the other ones.
