   Modified Files:   
   	src/sbbs3/smbutil.c   
   Log Message:   
   Rename msgbase files *before* packing to insure exclusive access   
      
   Even with the *.lock file created exclusively, there's still a race condition   
   where other processes could have the msgbase files open in which case the   
   final rename (e.g. from *.sd$ to *.sdt) would fail with an error and you'd end   
   up with a mix of files from before and after the pack operation.   
      
   This rename-first operation insures we're the only ones with the msgbase open   
   and since we have it locked, no one else should be able to open subsequently   
   either.   
      
   Updated the temp filename extenions to 4 chars now, so the operation goes like   
   this:   
      
                  ren                   pack                  ren   
   [*.shd/sdt/sid] -> [*.shd_/sdt_/sid_] -> [*.shd$/sdt$/sid$] -> [*.shd/sdt/sid]   
      
   Commented out the "duplicate index" message which was wrong (it's the header   
   that's duplicate, not the index) and a perfectly normal situation for mail   
   msgs to multiple recipients.
