[yt-dev] lost weak reference

I'll definitely make sure that it doesn't croak in the future (I
believe I've sorted it out since I sent this email-- I did, in fact,
do something dumb) but this bit took a while to run so if I _can_ fix
the thing I have that'd be sweet.  I did try re-attaching the
parameter file, but it didn't seem to take-- I think I'll just punt
and read papers today and re-run this analysis without the dumb-ness.

Thanks a ton!
