So like if the socket object couldn't be initted or added to the display
for some reason, it will call wl_socket_destroy() on the socket, which
will close the file descriptor and the fd lock.  So I guess this
question basically boils down to is it allowed for the client to close
the file descriptor it was given?

I'll defer to Sangjin on that but I should imagine that the client is
being given a unique file descriptor to use as it sees fit, including
closing it.  Even without errors, Wayland will eventually call
wl_socket_destroy at program exit, so the fd is destined to be closed
one way or another.
