Unfortunately multi-threading is not a feature of the Object Pascal 
language :( . Oxygen does have it ("parallel loop" and "future"). I do 
hope some day this  will be seen in fpc (based on a thread-pool 
implemented in the rtl).

Re Interfaces: Do you know a decent description of how to use Interface 
_as_a_language_feature_ (e.g. in fpc) completely independent of their 
use with certain OS-provided libraries ?

I once saw an implementation of a high bit count calculation library 
based in Interfaces to add reference counting to the objects used to 
hold the values. Do you suggest this Is a "correct use" of interfaces ?
