Tinyfecvpn x86 client CPU 占用100%

[garyxi008]

环境： Windows 10 64bit+ Virtual Box v6.0.14 +Openwrt (intel 32bit)--v18.06.5
Tinyfec版本：intel 32位版本，git version: 79d5e4d build date: Aug 20 2018 12:20:44
使用top发现 tinyfecvpn cpu占用100%，cpu占用和流量关系不大，静默40-50kbps或看测速iperf3跑满时，cpu都是100%。
CPU: 62% usr 37% sys 0% nic 0% idle 0% io 0% irq 0% sirq
Load average: 1.02 1.01 1.00 2/49 4033

使用strace -p tinyfecPID ,日志如下， 不停的访问/etc/localtime，
从ubuntu复制了zoneinfo文件夹至 openwrt的/usr/share目录下，并将Shanghai链接到/etc/localtime
ls -ali localtime， 重启后，tinyfec仍占用CPU 100%， openwrt WEB页面时区也设置成了上海。
