auto_increment and binary logging

[Mohil Chandra]

Hi,
I've gone through the document on auto increment handling in innodb. What I understood is that mysql uses a table-level auto-inc lock to provide consistency among records in master and slave when replication is enabled.

So, is this handling strategy(table level locking) is used even when the binary logging is not enabled??

Also, if the above is true, then the process will screw up only if there are too many simultaneous inserts ,and it will not depend on whether binary logging or replication is enabled or not??

Lets say if there are too many inserts, then will the selects on the table be affected??

Please clarify.
