I have almost finished writing the tests, but I am struggling on how to
create some special files:
- Creating block or character devices require mknod with root privileges.
- Creating a unix socket is not supported by the TCL library, and
require extra tools (netcat, socat...) to create one from the command line.

Here is what I use for now for the other types:
- Link: TCL function `file link`
- Regular: TCL function `open`
- FIFO pipe command line: `mknod myfifo p` or `mkfifo myfifo` which
doesn't exist on Windows.

What do you suggest? Should I avoid every non portable test cases, which
limits the tests only to links, regular files and directories?
