precedence

Hi, if an INSERT and a SELECT are done simultaneously on a mysql table which one will go first?

Example: Suppose "users" table row count is 0.

Then this two queries are run at the same time (assume it's at the same mili/micro second):

INSERT into users (id) values (1)

and

SELECT COUNT(*) from users

Will the last query return 0 or 1?
