thinking about it, mdev symlink support wouldnt help here at 
all ... /dev/std{in,out,err} are normally created by the init system as 
symlinks to /dev/fd/{0,1,2} ... and /dev/fd itself is just a symlink 
to /proc/self/fd

none of these things get kernel events to trigger the symlink creation in the 
first place ...
