I'd say that this should call for some scientific experimentation as it's
not clear to me at all how much 8 locks really is - for a very quick
session-locking request 8 might just be sufficient for a very high-volume
site. We'd need to make sure that the users understand that this is very
dependent on how the application is written, it's not like if you think
you have a high-volume site you should jack it up to 128.
