Multi threading support was Re: [fpc-devel] Russian locale information not compatible withFPClocale variables

Per instance would mean to need an algorithm to automatically define a 
new Mutex when creating an instance.

So maybe the TSynchronizedObject that might be the parent of all 
class(...) synchronized will define a TSynchronizedObject.Create that 
creates a Class-common or a system wide Mutex, while the create in a 
child class can modify this behavior to the use of an instance variable 
as the Mutex to have a per-instance protection.
