RunLoop vs Thread ?

[Yen-Ju Chen]

Hi,

 Does it have more advantage to using RunLoop than Thread
 in terms of non-blocking user interface ?
 Some tasks in CodeEditor take about 2-3 seconds depending on the file 
size,
 which block the user input and is annoying.
 Would it be better to implement these kinds task into RunLoop than Thread 
?
 I feel thread is more difficult to debug
 and need to be careful when coupled with GUI component.
 But I never touch RunLoop before and am not sure it is suitable.

 Thanx

 Yen-Ju
