Close all hang after linking many subplot axes

I am working on a project for which I create several plots with linked axes. When I try to close all the figures, I am seeing MATLAB hang for several minutes. I have traced it to having the axes linked. If I do not link the axes, close-all does not cause the program to freeze. Is there perhaps a better way to do this that would not result in MATLAB hanging?

I have tried to make the plots in both 2013a and 2012a and both have the same issue. Here is a code snippet which recreates the issue:

clc clear close all

y = rand(100000,1);

x = 1:100000;

hand = [];

for i = 1:100

   figure;

   hand(end+1) = subplot(1,1,1);

   plot(x,y)

end

linkaxes(hand,'x')

tic

close all

toc % Takes more than 35 seconds to close all
