Thanks!

Success-aside, I was still noticing a lingering issue (fixed
in the attached most-recent "watch_vop_remove3.d").

On "all night" runs, watching a tight-[infinite-]loop of
"touch /tmp/foo; rm -f /tmp/foo", I was noticing this:

I read-up some more on the difference between variables and the costs
associated with them (specific to FreeBSD; specifically that globals may
have some locking issues and should be avoided).

I made a new version of the script that changes all the variables to the
clause-local syntax (this->), and that fixed the issue (no more spurious
errors about invalid addresses).

Please find attached latest watch_vop_remove3.d, potential candidate
for commit to /usr/share/dtrace/.
