rethought it a little and I think I understand now...

I think simple reloading the segment thats used for TLS (which one is it?)
on fbsd at amd64 should do the trick. what do you think?

so instead of rewriting just the base address we reload the whole
segment. that should not be that hard. but I dont understand the connection
between fs/gs and the segment. is it that reloading fs_base resets
the base in the segment the fs points at?
