I see this with matlab-shell, when trying to tab-complete, in Emacs 23 
and emacs 24 on the Mac, both on Lion and on Snow Leopard.  I fired this
 up in the debugger and it looks like it gets stuck on a system call but
 
I&#39;m afraid I couldn&#39;t figure out any more than that.<br>

<br>

At first start, Matlab returns completions just fine, but after about an hour it starts hanging when tab is pressed. <br>

<br>

The function called on completion is here:<br>

<br>

And the accept-process-output call that hangs is here:<br>

<br>
I&#39;m using Emacs 24.0.93 from here:<br>
<a href="http://emacsformacosx.com/emacs-builds/Emacs-pretest-24.0.93-universal-10.6.8.dmg">http://emacsformacosx.com/emacs-builds/Emacs-pretest-24.0.93-universal-10.6.8.dmg</a><br>

<br>
Can I do anything else to help people track this down?
