Yes, I've done this before, too (in delphi, though).  If you add this to 
the TJSONConfig class, you'll have to keep track of which files are 
opened by different TJSONConfig classes, then lock them accordingly. 
This complicates things unnecessarily for a small amount of use cases. 
I can see how a derived thread-safe class would be handy for some 
people, but I'd implement this in my app, personally.  Much simpler.
