Metacat

trace level log for looping over EVERY pid in the system.

logging for each step of shared identifiers loading.

remove pause/resume - seemed to make metacat just hang on SM retrieval. Add more logging when returned SM is null -- want to make sure it is becuase the local node "owns" the pid key even though there is no value for it.

due to hudson build issue, did not actually end up testing pause/resume -- trying that again

pause/resume was not enough. trying shutdown/restart

experiment with lifecycle pause/resume. hopefully it prevents our node from taking ownership of any keys before we are sure we have them all.

increase logging and add back in the call to saveLocally() in case the SM object has already been loaded into the shared map but before this node came back online.

no need to call saveLocally explicitly since loading from the shared store triggers that behavior locally because of the configured listeners.
use an iterator over the shared identifiers in case this set is constantly changing.

make only one DB call to look up local pids - no need to do a pstmt for every single shared pid.

on init (start up) launch a synchronization thread that ensures all shared identifier entries have a corresponding local System Metadata entry.
