auto increment is really just a nice way of doing the following (really nice
way actually):
lock table x
select max(id) + 1 from table x
insert into table x values (newid)
unlock table x
this is under the assumption table x as 1 field called id which has a
primary key on it. and newid is the id recieved from the select.
so doing it manually with heap tables seems quite feasable just a little
extra work.

Subject: auto_increment vs. heap tables
