It's a bit of corner case but should okay. As some point we should just 
get rid of this code completely and re-implement the list method to use 
the new file system API.

I checked the MSDN docs and free(NULL) is a no-op as it is elsewhere so 
I think this is okay. Clearly if either is NULL then memory is 
completely exhausted and the VM will likely crash/terminate anyway.
