#42 Trousers should be able to terminate even if clients hold connections open
I'm seeing this issue in trousers 0.3.11.2 but looking through the current code doesn't seem to suggest this has been changed at all.
If I have a client that holds open a session continuously it will block trousers from shutting down when it gets SIGTERM because tcsd_threads_final waits on all the threads which are blocked on the socket connecting them to clients. It would be nice if trousers could still cleanly shutdown in this case, even a solution where it waits for a bit for threads to finish before just closing the connections would be nice too.
It seems the client returns TSS_E_COMM_ERROR if I SIGQUIT trousers. I'm not certain what the spec says about this kind of situation, but that seems a decent enough signal to just re-open the connection with.
