You've missed the point entirely.  Our current FD_SETSIZE is no longer
aequate for current machines. I'm asking to raise it to a more
reasonable value, for *netbsd-supplied binaries* as well as user apps.

No, it isn't that simple. (The issue you think you're ansering _is_
that simple, but that's not what I'm asking).

Oh, come on. Ultrix ran on vaxes. Last I used Ultrix, it had an
FD_SETSIZE of 4096 (and a default max-open count of 64, just as
we do now).  This argument isn't credible, lt alone compelling.

Unless you're arguing that IPv6 is also too expensive for these machines?
