NSCM is supposed to detach the session only when the screensaver 
locks the screen.  Specifically NSCM detaches the session when the 
screensaver invokes PAM, which indicates that the user will need to 
reauthenticate in order to regain access to the desktop.  If the 
screensaver only blanks the screen or puts up some screensaver eye
candy then NSCM shouldn't even be aware that that's happening.

Yes, absolutely.

No, it's just always supposed to always work the way you want it to
work.  Do nothing when a saver starts, detach the session on lock.

Are you sure that you have your screensaver configured to blank some
time ahead of when it's configured to lock?  Can you verify outside 
of NSCM that the screensaver really does blank ahead of locking, say 
in a smartcard session or on the console or in a remote X login?

Can you capture a 'truss -f -u""' of a screenlock process at the
time it detaches a session as a side effect of blanking the screen?
That'll show you whether it's calling PAM at that time.
