Getting -mix output from more than thread 0

Hi,
I find that the -mix output of SDE is very useful. Unfortuntately it only outputs by default for thread 0. Is there a way i can get it to output for more than 1 thread? I've tried:

sde -mix -p -mt -- "exe"

but it doesn't output stats for all threads. I also tried to specify the number of threads via "-mt 4" but that is not the correct usage. In the -phelp it states by default it is 1, how do I change that?
