Is this new for 2.x? I know we could connect during a restore under 1.5.

point 1 - shutdown state is not stored into backup.
During restore DB is itself in single-user mode, so, noone can connect
until restore finishes. If there was error, gbak will not turn
db into online state (to indicate error).

Also, Sean suggested correct scenario, because, when you delete
DB on Linux, and there is at least 1 connected user (with single-mode
shutdown), and create new DB with the same name (by restore),
there will be 2 different (!!!) db files - old one and new one.
I don't remember what problems this may lead to, but suggest to avoid
such situations.
