Because the plots are only used at the time they are transferred to the http client (i.e. are dumped by a python script to stdout), I have to delete the plot's .png file which has been created by savefig() immediatly after the plot has been transferred.

when using the GD backed, you can write directly to a stream (in your case
could be sys.stdout).. the same functionality has not been implemented for
agg yet (last time i checked)..  i needed this before,
and hacked it up for GD in the early days (didn't even have agg back
then).. i think it would be great to have this implemented for agg, but i
think noone got around to doing it yet...
