I think xorp can be made stable, but it will likely require dev work & testing to deal with bugs in
how you want to use it.  In general, it is much more stable if you create the
config file as you want it and then don't do too much with xorpsh.  I've fixed the problems
with how we do our own dynamic config of xorp...but obviously more remain.

At the least, please open a bug report for what you found (with backtrace & xorp log, etc).

No arguments with this, but I have no time or interest to re-write all of this.  If
someone else wants to fund this or work on it, I'll be happy to work with them.

I'd be curious to know what you find if you find something better...

Thanks,
