I went through the code again, but I did not see any obvious file
descriptor leaks.  I did, however, find a few other bugs.  I've posted a
new version of the battstat patch at
http://www.marcuscom.com/downloads/patch-battstat-acpi.  Please try this
new version, and if you see those maxfiles messages again, get the
output of lsof for the battstat process (i.e. lsof -p <PID of
battstat-applet-2>).

As for the backtrace below, it is useless.  It doesn't look like a crash
in the battstat code first of all; and secondly, there are no debugging
symbols.
