[svn] * src/client.c: Only bail out of fetching multiple articles if the connection fails. If we do get a status from the upstream server note it and see what is reported for the next article. Otherwise failure to retrieve one article will cause all successive article fetches to fail even through they would succeed if tried. * src/lock.c: Fix assert in lazy locking. If another noffle signalled us to release the lock at the next close, and then repeats the signal so that it arrives during LOCK_closeDatabases, the signal handler was trying to close the databases again.
