*boggle*

Care to explain how that "namespace" is different from devpts instance?
IOW, why the devil do you guys ignore Occam's Razor?

Frankly, this nonsense has gone far enough; I can buy the need to compensate
for shitty APIs (sockets, non-fs-based-IPC, etc.), but devpts *is* *a*
*fucking* *filesystem*.  Already.  And as such it's already present in
normal, real, we-really-shouldn't-have-any-other-if-not-for-ancient-stupidity
namespace.

Why not simply allow independent instances of devpts and be done with that?
