[sql] select queries are blocked and not executed concurrently (sqlite)

[rap2hpoutre]

Using this short code:

console.time("long");
console.time("short");
// This takes 3 seconds
db.select(
  "WITH RECURSIVE cte(x) AS (SELECT 1 UNION ALL SELECT x + 1 FROM cte LIMIT 10000000) SELECT count(x) FROM cte;"
).then(() => {
  console.timeEnd("long");
});
db.select("SELECT 1;").then(() => {
  console.timeEnd("short");
});

I have to wait the end of the first query to finish its execution to get the second query result.
It's as if each query is waiting for the following one before running itself.

Here is the result:

long: 3580.368ms
short: 3580.434ms

As you can see both query took 3.5 seconds even if the second one is fast.

Could this be fixed?
