Currently ncld has a bug that causes it to report a session failure
when session was not open yet. So, if a session fails to open,
application crashes while trying to print the SID. This problem
made this crash occur easily.
Unfortunately for us, there's more to it. If the library opened
session, but is pre-empted before ncld_sess_open returns, the
same situation may occur legitimately. So this check is still
needed, unless we radically change the locking strategy.
