because AFAIR the softint infrastructure uses bitmasks, and the
bitmask is of finite size. I don't remember the details, but this
prevented me from upgrading some servers to netbsd7: in netbsd7 bridges
uses several soft interrupts (this was not the case in netbsd-6), and I have
too many bridges. in netbsd-8 bridges have been fixed to use less
softints, so I can run netbsd-8.
