[Users] Claws closing slow ?

[Michael]

Referring to http://lists.claws-mail.org/pipermail/users/2012-January/001182.html but this is probably just another topic.

More important to me would be to find out why claws and firefox are closing so amazing slow with kernel 3.x, and Paul might have a point, if there was any file system operations related to that closing, and the ext3/4 FS driver changed in the kernel. 

So i wonder, is claws doing something causing disk traffic when closing ?

It might be unrelated, but i had this debug messages at closing time (link above):

With kernel 3.x and slow closing: 

MH scan required, folder updated: /home/mi/Mail (1327275788 > 0)

With kernel 2.6.x and fast closing:

MH scan not required: /home/mi/Mail/queue (1327276974 <= 1327276974)

Would anyone be so kind and explain what this is about and why there would be this difference ?
