[syslinux] Problem with menu.c32

[J.H.]

It looks like there's a bug in menu.c32, specifically dealing with the 
number of times you change menu pages.  When a total (including the 
default load) of 28-29 loads of menu.c32 occurs the whole system will 
hang (ctrl+alt+del doesn't do anything).  Looks like it's a problem 
concerning the number of file handles or something along those lines.

The easiest way to duplicate the problem is by creating two txt files 
with the following:

---------
even.txt:
---------
MENU TITLE ** EVEN **
LABEL odd
         MENU LABEL ODD --->
         kernel menu.c32
         append odd.txt

-------
odd.txt
-------
MENU TITLE ** ODD **
LABEL even
	MENU LABEL EVEN --->
	kernel menu.c32
	append even.txt

and cycling between them for about 28 times.
