if by "elegant" you mean "already built-in", the answer is "no", to my
knowledge.

on the other hand, assigning a negative P.Type will automatically drop
out particles from all hydro loops.
anyway, loops doing gravity are generally written as
for(i = 0; i < NumPart; i++)
{
}
with no check on the Type. You should eventually put it.

simply hiding a particle should end in some problem about conservation
of momentum, angular momentum, energy etc.. probably i don't understand
exactly your plan.
