"""Test load_session for resource leaks |

|
|
| 248 |
|
The load_session function had a resource leak in that it created |
| 249 |
|
cyclic references. The objects would have been eventually |
| 250 |
|
collected by the garbage collector but too late. One symptom is |
| 251 |
|
that when layers are removed so that the last normal reference |
| 252 |
|
owned indirectly by the session to a shape store goes away, the |
| 253 |
|
shape store is not actually removed from the session even though |
| 254 |
|
the session only keeps weak references because there are still |
| 255 |
|
references owned by the cyclic garbage. |
