[elephant-devel] How should I handle a controller-lost-error?

So long as you follow Leslie's suggestion, multiple process locking is  
fully supported by BDB (via a shared memory region managed by the  
library).  If you want to do something like this across multiple  
machines, you'll need to use the slower, but more scalable Postmodern  
store.

 From a casual user's standpoint, I think it's in pretty good shape; I  
use it for customer facing projects quite reliably.  From a software  
engineering standpoint, the last 10% of feature tuning, code cleanup,  
and documentation is going to be a bear to get done for 1.0!
