If most RPCs are normal messages from a task having a send right to
one having a receive right, it might improve the performance to map
the arrays to every task in read-only mode, so that it can check if an
IPC is valid by itself. In this case, a sending thread does an IPC to a
receiving thread directly somehow, so this makes the context switches
half. This isn't good for "send once" rights, but I don't think "send
once" rights are used so often.

However, I'm not sure if L4-Hurd needs a central port right server. Is
it really necessary?
