[yt-users] particle read error

[Matthew Turk]

Hi Dave,

Last I remembered, particle reading from clumps shouldn't work; that
being siad, I am surprised that two subsequent calls do or do not
return particles or throw different errors.  To be clear, you're doing
something like:

1) unpickle
2) read particles, get error
3) read particles, get particles

Right?
