I believe that the MFC is now complete.  If you run into any problems with 
this tool, please file a PR and I'll try to address it.  Two areas where I 
would like to do future work, and would also greatfully accept contributions, 
are:

(1) Adding libkvm support, allowing procstat to be used on crashdumps.
(2) Adding a signal information dump mode, providing information on what
     signal handlers (etc) have been set to non-default dispositions.
(3) Add user thread stack tracing support similar to kernel thread stack
     tracing support.
