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.
