In master, run tests in pkg/ttl/ttlworker takes 34.5s:

> X="run pkg/ttl/ttlworker" make ut
cd tools/check; \
	GO111MODULE=on go build -o ../bin/ut ut.go
cd tools/check; \
	GO111MODULE=on go build -o ../bin/xprog xprog.go
GOBIN=/Users/wangchao/Code/pingcap/tidb/tools/bin GO111MODULE=on go install github.com/pingcap/failpoint/failpoint-ctl@9b3b6e3
tools/bin/ut run pkg/ttl/ttlworker || { find $PWD/ -type d | grep -vE "(\.git|tools)" | xargs tools/bin/failpoint-ctl disable; exit 1; }
