And how is he supposed to know that this only one way of using a TList with
multiple threads and that are plenty of other ways?
Answer: By first reading a tutorial/book about multi threading, including
critical sections etc that explains how to use thread unsafe code with multiple
threads. 
Of course it would be nice if the section about thread safety has a link to such
a multi threading tutorial. 
And of course you are free to provide examples for the documentation. I know,
you have no time for that.

 A new term would need explanation too.
