This sounds reasonable.

I'm not sure if it can easily be done in ERP5, but years ago I solved 
similar problem in Tomcat-powered application by adding a unique token 
(generated from the system time) to each request that should be 
prevented from double execution. Last token was remembered on the 
server, and when a request with the same token came, server discarded 
such a request. It works regardless ot the browser settings.

I think it shouldn't be reverted, as preventing user from double 
execution of the request is very important. However, sometimes it makes 
no sense, for instance in raport dialog, where user could have a chance 
to re-launch the report with different settings (this was the case that 
made Mikolaj post his question).
The nicest thing would be the ability to enable or disable such 
functionality per dialog.
