Subject: rm: cannot remove `???': No such file or directory

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...
