Dear all, 

Currently, whenever inmate_main() terminates, the cell_state is left 'running'. 
I was wondering whether there is a specific reason to do so, and what that 
reason would be. Especially when the cell is set to 'locked' this behavior is 
unexpected, as the cell cannot respond anymore. 

Attached is a very minimal patch which sets the cell state to 'shutdown' upon 
calling stop(). I understand that this changes the behavior of the inmate 
library, which can be considered a public API in this project, so I would 
understand if this change is undesirable.

I had one consideration remaining for the implementation of this patch. Is each
cell guaranteed to have a comm_region? Currently, setup.c seems to assume so. 
The function stop() now checks whether there is one, as I expect it to be
impossible to place the comm_region at address 0. If this is guaranteed, we 
should remove the check.

Looking forward to hearing your thoughts, 

Best regards, Bram Hooimeijer
