[yt-users] pickle

[Matthew Turk]

It might also be worthwhile to see what, exactly, core is ...

print core

Depending on how it is loaded/unloaded, it might be a tuple of the
parameter file, or might be something slightly other than you are
expecting.  This comes about because it tries really hard to make sure
that the parameter file doesn't disappear.
