GIT+CYGWIN annoying test failure

[SungHyun Nam <goweol@xxxxxxxxx>]

Hello,

First of all, this problem always existed to me. I was lazy to report.
Please check the failure logs and my GIT build script below.
My build script runs 'make test' twice because of this annoying failure.
It does not mean that the first test always failed, but very often.
If it occurs, the first test failed at 't1000-read-tree-m-3way.sh'
always. And in this case, 2nd test always succeeded.

Thanks,
