I think I will first try to create my big list in parts. Indeed it not
critical to have all the list items visible right from the beginning.
Instead I can use a timer to split this heavy operation to smaller tasks and
so give the other parts execution time while the timer is running. Should
have figured this out by myself... Thanks for your tips!
