When process forks, status tags are not equal to 2

This change is needed:

```
"""Takes in list of <status> blocks"""
- if len(el) != 2:
-     raise ValgrindFormatError("Incorrect number of ‹status> tags.")
+ # Temporary patch for valgrind with fork
+ # if len(el) != 2:
+     # raise ValgrindFormatError("Incorrect number of «status > tags.")
```
