I just understand, that its wrong to test via boniee++ with default
params, which required write 300Mb data, neo have mtd just 256mb, and
both fs becomes **very** slow near ENOSPC.
So, I rerun all tests with -s 32 -m 16, also I tested ext3, and ext2
in sync/async mode.

Can somebody run
bonnie\+\+ -u 0:0 -s 32 -r 16
on jffs2 with at least 64Mb free space?
Also I want repoint people about
http://shr-project.org/trac/ticket/445, we should ALWAYS mount
uSD/usb-etc async.
