System file max graph

[Grew]

Hi,
When you create a new graph on the fly (map_new, map_clone, etc...), it puts this graph on the system file.
I think this file is a ordinary FPG file, thereby, the maximum amount of graph it can contains is 999.
What to do when this maximum is reached ?
Is there a way to clear the system file ?
Is there a way to say to bennu to put the files created on the fly in a particular FPG ?
Is there a way to free the index of a particular graph created on the fly in the system file (for exemple when the process who created the graph dies) ?


Thank you for you help !

Update :


After some tests, it appear that the maximum is 1255. When this maximum is reached and you try to create a new map, the counter restarts from 1001, but it's blocked at 1001 ! If you try to create graph on the fly after that, the counter is still to 1001. It causes many bugs with the other graphs (which are loaded from FPGs files).
