cut doesn't buffers everything, grep is to blame. If grep output to a
non-terminal (e.g. a pipe) it use buffers of 4k (don't remember the
correct value). Unfortunatly, I don't know any way to get around
this. Maybe you can use awk (or perl) to combine the functionality of
grep and cut in the above line.
BTW: A parameter to every program enforcing line-buffering instead of
block-buffering would be great. In this case grep would be called with
this parameter and everything works fine again.
I haven't lost my mind -- it's backed up on tape somewhere.
