#3 possible memory leak

i've just started using pympi and it seemed at first that
everything was working great. Then, like didier, i noticed
that memory kept on increasing over time. I think I
finally narrowed it down to some of the mpi directives. If
I perform the following line of code multiple times:

local_ODEs_now[:] = mpi.scatter(self.ODEs_now)

then the memory on all nodes increases each time, with
the memory on the root node increasing at a greater
rate than the compute nodes.

is there any way i can prevent this from happening?

thanks,

    There was a problem in one of the utility
    routines that collected data to a central
    place. This same leak was killing mpi.reduce
    and allreduce too.

    Think it is fixed now.
