flash file system for production use

[Michael Palme]

okay... thanks for the answer.
i will do some serious testing myself. what would be a real life 
scenario ??? is a random loop with creating, writing and deleting files 
mixed with mounting and unmounting and some random powerfaults???

i think the salesdroids- thing will not work: they only thing they want 
is to get a product to the market as fast as they can...
