vinth2p memory leak?

Hello,

I'm having memory problems when calling vinth2p repeatedly, see code
snippet below. After some iterations (about 80 in my case), memory
fills up and the code eventually crashes.
I'm using PyNGL/PyNIO 1.3.0b1 on Mac OSX 10.4, both Intel and PPC
machines give the same problem. However, the problem does NOT arise
when I run on Linux x86_64.
Thanks,
Rodrigo

=============================
from numpy import *
import os,glob
import Ngl
import Nio

File = Nio.open_file('cam_data.nc','r')

time = File.variables['time'][:]
hyam = File.variables['hyam'][:]
hybm = File.variables['hybm'][:]
p0mb = File.variables['P0'].get_value()/100.

pmin = 50.
pmax = 1050.
dp = 10.
p = arange(pmin/dp,pmax/dp+1)*dp

for l in range(len(time)):
     x = File.variables['U'][l,:,:,:]
     ps = File.variables['PS'][l,:,:]
     xi = Ngl.vinth2p(x,hyam,hybm,p,ps,2,p0mb,1,False)
