Overview

S60 phones use cooperative multitasking. You call e32.ao_yield() here and there to let other tasks run before they return back to you. e32.ao_lock() also plays a role when you wait for callback.

Code

import e32   #import module
from SomeBigLibrary import * # takes a very long time !
 
e32.ao_yield()
# your codes follow
