Mutex lock - getting information from pidin

Is it possible to get more information from pidin that will tell me more
about a mutex lock problem? Here is an example of a thread that is mutex-
blocked:

16707628 2 myprocess 10r MUTEX 16707628-06 #1

I have several mutexes so if it is possible to find out which mutex it is
blocked on, that would be helpful.
