This is not the same.  This hangs because of a deadlock.  Shell runs 
synchronous, and hangs until the command output has been read.  But when emacs 
does that, it can’t respond to the request from xclip.
It also only hangs if Emacs owns the primary selection, not if another process 
does.

It is because there is a clipboard handler running, i.e. Emacs does not answer 
to xclip in this case.
