I think the same question applies the bytecompiler only:

Do we have to write the temporary .elc files out to disk at all before
producing and renaming the final .elc?

In general the last action is good to be a file rename as this should be
atomic.  But that said yes, _when_ we write the temporary file is up to
us.  Again this is not strictly a native compiler issue, just with the
native compiler is more likely to be encountered.

Best Regards
