It seems like Enhydra's session persistance is more useful for managing 
the amount of memory used by user sessions than it is for preserving 
sessions when restarting.

If you set (for example):
SessionManager.SessionHome.Mode = PAGE_TO_DISK
SessionManager.SessionHome.PageDir = /path/to/tmp
SessionManager.SessionHome.PageThreshold = 50
SessionManager.SessionHome.SaveOnRestart = true

then sessions are preserved properly when restarting, if you stop/start 
your application with the admin console.

If you don't use the admin console, you could try setting 
SessionManager.SessionHome.PageTimeThreshold to some low number to 
force sessions to be paged...but this doesn't exactly seem like a 
graceful solution.
