After selecting a db with the select command, after a certain idle time (not sure how long exactly), the console, even though still indicating e.g. servername:9 > will internally connect to db 0 and not to the last selected db.

Steps to recreate:

1. Connect to the console
2. Make sure keys are stored in e.g. db 9 and db 0
3. servername:0> select 9
4. Leave console idle for a reasonable time
5. servername:9> flushdb

Expected outcome:
db9 is flushed
Actual outcome:
db0 is flushed
