Done.  The idea is good, but I wasn't quite happy with your code.  It's
hard to read and it's more complicated than necessary.  For instance,
you only handle one page at a time, but your code keeps an array for two
page information entries around for no good reason.

I checked in a simplified version of your patch.  Please have a look.
Since the code in question is in the public domain, it doesn't require
a Cygwin copyright assignment.


Thanks,
Corinna
