Cannot read property 'info' of null

When piping a CursorStream, I get the following error after about 10K documents:

/home/deploy/test/node-EmailBlast/node_modules/mongodb/lib/mongodb/connection/server.js:484
        throw err;
              ^
TypeError: Cannot read property 'info' of null

    at TCP.onread (net.js:367:14)

This is the offending block of code in server.js starting @ line 322:

        // Locate a callback instance and remove any additional ones
        for(var i = 0; i < server.dbInstances.length; i++) {
          var dbInstanceObjectTemp = server.dbInstances[i];
          var hasHandler = dbInstanceObjectTemp._hasHandler(mongoReply.responseTo.toString());
          // Assign the first one we find and remove any duplicate ones
          if(hasHandler && callbackInfo == null) {
            callbackInfo = dbInstanceObjectTemp._findHandler(mongoReply.responseTo.toString());
            dbInstanceObject = dbInstanceObjectTemp;
          } else if(hasHandler) {
            dbInstanceObjectTemp._removeHandler(mongoReply.responseTo.toString());
          }
        }

        // The command executed another request, log the handler again under that request id
        if(mongoReply.requestId > 0 && mongoReply.cursorId.toString() != "0" && callbackInfo.info && callbackInfo.info.exhaust) {
          dbInstance._reRegisterHandler(mongoReply.requestId, callbackInfo);
        }

Notice that callbackInfo could be null.

Made a branch mistake. Will reopen. I'm WAY too tired to be fucking with this shit.
