Not easily. When you open and write a file, there are two separate
system calls -- open() and write().

JFFS2 is entirely synchronous -- we ensure that the results of a system
call have hit the medium before we return to the user. So optimising out
the 'metadata' node which holds the permissions and timestamps etc. of
the new file, and which exists before any data are written, isn't very
easy.
