Your suggested improvement was broken for empty thread objects -  
array_replace requires at least one array.

Additionally, there's significant overhead involved with  
call_user_func_array() and array_replace().  Better just to use the  
array union operator - benchmarked at 25% faster on a 500,000 message  
thread object, with the same maximum memory usage.
