Want `bunyan -n app` to DTrace my clustered node app about node-bunyan

dap: "FYI, I believe curpsinfo->pr_psargs only has the first 80 chars of the exec string. I'm not sure if you want to document that or what."

dtrace -x strsize=4k -n 'bunyan*:::log-debug/strstr(curpsinfo->pr_psargs, "$NAME") != NULL/{printf("%d: %s: %s", pid, probefunc, copyinstr(arg0));}'

So, hrm.... not sure what exactly would be best. Perhaps instead bunyan could shell out, find the full cmd more reliably and use those pids.

Also included to overload -p PID|NAME for this

Boo: https://discussions.apple.com/thread/1980539 Effectively no curpsinfo->pr_psargs in Mac's dtrace.

This is in bunyan 0.16.6.
