No, the node stays in checkedOut state until the application calls
checkin again.

You can handle this problem by either checking for the checked out
state in other sessions (before they try to access the node), by
writing some kind of on-client-exit handler that ensures all documents
are checked-in automatically (if that is desired) or some background
thread that looks for nodes that are checked out for a certain period
of time and check them in. Although I would think that the changes
made by a client that did not close the session properly should not be
trusted...
