Saving shibd session state during restarts

[Lenny Miceli]

Thanks for the info Jacob, the thread you mention sure does persuade me 
not to use memcache.  So my options to resolve this problem are either 
use a "beta" DB plugin with it's own set of problems or take time to 
program shibd to dump it's cache on shutdown and read it in on startup.

Also, thanks for the reply Kevin.  Since you state, if we went memcache, 
we'd be in the minority with little or no support that puts another nail 
in the coffin with using memcache.

Thanks to you both for your additional help/info.
