i used this script, a little clunky but it got the job done
```bash
for file in `find . -type f -print | grep '\.go'`; do
sed '1,/^\/\/ limitations under the License.$/d' $file > $file.tmp;
result=`cat $file.tmp`
if [[ result != "" ]]; then
gofmt $file.tmp &> /dev/null;
if [[ $? == 0 ]]; then
mv $file.tmp $file && gofmt -w $file;
else
rm $file.tmp;
fi
else
rm $file.tmp;
fi
done
```
I think this will improve the transaction response messages Kuba
mentioned where it was an empty transaction instead of a nil or not
there... if not it should make it easier to do that anyhow.
also adds a "noSleep" option to the server command to avoid the 5
second sleep we introduced on startup for non-coordinator cluster
nodes. The sleep doesn't seem to be needed in the tests and makes them
much slower.
