master_0505_38473d1
Problem Description：
10 users register metadata concurrently, but iotdb starts to register after 
more than 20 minutes
(即：10用户并发注册元数据，iotdb 20多分钟才开始注册 , log输出set storage group to..
create storage group schema folder..）

机器信息：
fit 192.168.130.1（iotdb 8C32G）/ 2 (bm)

iotdb配置参数：
mlog_buffer_size=10485760
schema_engine_mode=Schema_File
其余参数默认。

bm配置参数见附件（2个配置都可以复现）。

日志（24分钟后才开始注册，rel/0.13没这个问题，可以排除benchmark的问题）：
