 No, it is not another approach :) This should be applied _as_ _well_.
 I just forgot to check if syscalls have made restartable or not. Of course
 they should.

 It does not. This will help only if we are already in the syscall but no
 data were transferred yet. If even the only byte is passed - the write() will
 be interrupted. Same situation with read(). I do not remember though how about
 sendfile()... should be the same there.
