I don't understand how the execution time is relevant for this issue.
Your handler must outlive your async. event, i.e. the object you pass
to async_write must be alive when the write operation is complete.
You can achive this in various ways, among them - by passing a smart
pointer to a heap-allocated object, or by passing an object by-value.
