Back in the dim and distant, when "computers" were expensive, having
multiple users with compilation rights on one Forth system was common.
When "personal" computers became common, most Forth systems assumed a
single user but multiple threads. This has been the dominant model in
embedded systems for a long time. 

The only application when we really have to consider dictionary access
is when handling web servers that use the on-board Forth for
server-side scripting.
