Change the fulfill hook to accept a single object of the form {src:, address:}. Rename actualAddress -> address throughout. Probably "src" will be renamed a little later.
Update build.sh.
Temporary hack: keep old URLs alive for now.
Simplify rationale on eager calls to fulfill/reject callbacks.
tidying in comments
Remove "it would be nice if" comment.
Markdown interprets <m_0, e_0> as a tag; rewrite comment to [m_0, e_0].
Assign responsibility for multiple `export *` delcarations to the $GetLinkingInfo primitive.
For determinism, whenever a Load needed by multiple LoadSets finishes loading or fails, finish/fail all those LoadSets in timestamp order.
Set script/module dependencies at link time. They are needed at evaluate time.
