Should I model a latest end for an asynchronous task?

[Fred Lunaspa]

Hello,
 
Can someone tell me if it's good practice to model a latest end for a
asynchronous task in order to handle terminating events that are not raised
within a specific timeframe? Or should I not model this explicitly in my
workflow?
 
Regards,
