You can make your application know when it has ended abnormally...for example, when each user goes into the program you can write a little file (semaphore) to the disk, and delete it when the program exits normally. You can figure out who is the most offensive party *grin*, and have the system rebuild all indexes if it detects an abend.

That'll teach em :)
