They can be issued concurrently. Tor doesn't care.

Also, with HTTP/1.1 pipelining to the actual website, we just need to
open a single TCP stream (one RELAY_BEGIN) and we can then fetch many
pages in a row.

I'm not sure if this is better or worse than fetching them in parallel. I
suspect Juliusz (the polipo developer) has opinions :), and I'll defer
to him.
