You can not perform a "hot remove" of links.  Maybe I just wrote how
you can do it some time ago to somebody else. Please take a look to
the archive and you can find the answer (may near when I've post
the blank player).

Anyway the modifications of the graph when is running is a little bit
tricky (I wrote it but the result don't give a lot of improvements from
the performances point of view); the standard implementation is
stop the ticker, rebuild the graph and restart it.

I hope it can help you
