server-buffer-clients is nil (Emacs 22) when find-file-hook is run. That
makes it impossible to test if a buffer has clients at that time.
Could this please be corrected?
(I am still using and old Emacs 22. Perhaps this has already been changed?)

Seems difficult to solve this one directly: find-file creates the
buffer, so it first creates the buffer then calls find-file-hook then
returns the buffer to server.el (via find-file-noselect): server.el
doesn't get a chance to set server-buffer-clients early enough.
Did this used to work differently in earlier versions of Emacs?

I do not believe it worked differently.
I am using a not-so-very-beatiful work around currently ;-)
