Re: The mmap stuff definitely needs more eyes!

Hi there,

This one works on the Nokia 770 device!

http://pvanhoof.be/files/camel_folder_summary_with_mmap_fixes11_data_alignment04.diff

So my real target has finally been reached. Using this stuff, it should
be possible to display huge folders using tinymail on a Nokia 770. 

With huge I mean: I'm expecting to support more than 20,000 headers per
folder. I don't know .. in theory it should even work with 100,000 or
more headers. But there's theory and reality. Lets test?

ps. It's of course going to take a while to receive the summary of such
a folder over wifi. 
ps. I only tested this (on the device) with the imap implementation.
ps. Other people, please test this?
