I am sending the transactions via a two simple curl commands joined with:

Or in the case of sending a single transaction, just the first of these two commands &&'d together.

I actually see this behaviour with the InstantSeal engine as well.

It is an issue that will be resolved once new engines are introduced. These two can only trigger resealing when new transaction arrives and can not start sealing if sealing is ongoing.
For now the workaround is to introduce a small delay between submissions.

Closed via #3426 (parity --chain dev should now seal all)
