hello,
I did a simple/dirty benchmark on multiple file systems, and ext4dev
encounters some problems recursively removing linux tree... tested with
default and multiple altered option sets of mkfs.ext4dev and/or mount
options - the same story :(
I guess there are locks on files where modification is committed to fs,
but not yet flushed to disk or something like this. anyway this behavior
is fatal for any temporary file operations...
