It doesn't actually hang the server, rather what
happens is that it outputs to terminal with a server
grab.

So, if you run it in a xterm (etc.), you get a:

 X server blocks on restest
 restest blocks on terminal
 terminal blocks on X server

loop. If you ssh into your box and kill restest things will
be fine.

The workaround is to redirect the output to a file:
