Cool!

What are the specific behaviors of AUTO_INCREMENT for HEAP?

- Are values that are deleted from the top of the sequence reused
   (like ISAM and BDB) or not (like MyISAM and InnoDB)?
- Can you specify the initial AUTO_INCREMENT value with CREATE TABLE
   or change it with ALTER TABLE (like MyISAM)?
- Can you use AUTO_INCREMENT with a composite key to generate multiple
   sequences within a single table (like MyISAM and BDB)
- Does DELETE FROM tbl_name (no WHERE clause) reset the sequence counter
   to 1?
