Yes. It only erases 1 sector in that time.
The debugging output of JFFS2 during those 18 seconds, preferably annotated

I guess that I can manually do a echo "9" to the /proc/sys/kerne;/printk to
turn debugging on at that time- or do you want it on since the beginning. That
will be a huge file.
It already takes me about a whole day to get the file system filled up to
capacity- where it misbehaves.
