I agree with all the points you and Pavel you talked about but I don't 
feel comfortable to have the current process to switch the pid namespace 
because of the process tree hierarchy (what will be the parent of the 
process when you enter the pid namespace for example).

The answer is - the one, that used to be. I see no problems with it.
Do you?

But perhaps it could be named "namespacefd" instead of nsfd, to reduce 
potential clashes (because glibc will usually just use the same name 
when making the syscall available as a C function).
