I noticed that when creating many `GDALRasters` in a single context, the
memory allocated to GDALRasters does not get released properly. For
instance, the following loop as an ever growing memory consumption:
{{{
from django.contrib.gis.gdal import GDALRaster
n = 1000
for x in range(n):
rast = GDALRaster({
'driver': 'MEM',
'width': 500,
'height': 500,
'nr_of_bands': 1,
'srid': 3086,
'origin': (500000, 400000),
'scale': (1, -1),
'skew': (0, 0),
'bands': [{
'nodata_value': 10,
'data': range(500**2)
}],
})
}}}
Adding `rast.__del__()` to the loop solves the problem, but I guess that
should be automatic.
