In case a runtime error occurs, the thread object stores the exception 
which occured, so before destroying the threads try something like:

|if Assigned (t1.FatalException) do
|   WriteLn (StdErr, t1.FatalException.ClassName,
|                    t1.FatalException.Message);

Alternatively you can embrace the Execute method with a try-except 
statement.
