Sigh.... reading the Delphi docs now and I understand the name

Not entirely true on windows. There are 2 ways to name a thread. The 
first is indeed for debugging only since it is passed to the debugger 
though some predefined exception.
The second is recently introduced by the Get/SetThreadDescription 
functions. The Get function can be used by other (non debugger) 
applications. Some applications already set the description this way.
