构建Go from source时测试失败

Question

当我从源代码构建Golang时，我无法传递构建测试：

hg clone -u release https://code.google.com/p/go
cd go/src
./all.bash

....
ok      net/url 0.005s
ok      os  0.595s
--- FAIL: TestExtraFiles (0.12 seconds)
exec_test.go:230: TestExtraFiles: Something already leaked - closed fd 3
exec_test.go:403: Run: exit status 1; stdout "leaked parent file. fd = 10; want 9\n", stderr ""
FAIL
FAIL    os/exec 0.822s
ok      os/signal   0.511s

请帮忙。这是在我的webfaction共享机器上。

根据issue 3001，CentOS 5 / RHEL 5中存在一个错误，基本上内核忽略了O_CLOEXEC。

所以要么忽略错误（坏主意），要么转移到更新的Linux版本。
