As Tom points out, long operations arn't guaranteed to be atomic, but I 
think that's unlikely to be the problem here.

Something like:

patch -l -p(n) < file.patch

If you're applying the patch to an already built source tree, you should 
just be able to type "make install" and it will only rebuild the parts 
of libjava that have changed.
