Subject: Re: Pending patches for MT-fork stuff

I was experiencing a hang when calling setreuid from a thread on musl
1.2.1 as well as on master with these patches applied. I have attached
a Go program which hangs when run as the root user outputting only:

    main.go:31: Calling setreuid

Whereas with glibc the setreuid call completes successfully, with the
following output:

    test.go:31: Calling setreuid
    test.go:40: Running command
    test.go:45: root
    test.go:46: Command complete

I am happy to help troubleshoot the issue, yours kindly, Jesse
