Description

I found recent Python supports these file types:
S_ISDOOR
S_ISPORT
S_ISWHT
even they return False always.

What about supporting them in Ruby?

Is there any OS/platform supporting those?

Doors are a thing on Solaris.
Event ports are also reportedly a Solaris thing, but all references seem to be about the Python feature. S_ISPORT macro doesn't exist on my Linux system.
Whiteouts are used for unionfs-like file systems, but SO claims that official Linux FSs don't use this type.

Update: event ports are mentioned in Solaris docs, but that documentation is broken.

Solaris mentioned, so I'm bringing up illumos. Ruby has an OpenIndiana port, so this could be tested there :P
