top 2.5beta7 (this is the last version) doesn't work on NetBSD
1.3:

   top: cannot read nswap: kvm_read: Bad address
   top: cannot read nswdev: kvm_read: Bad address
   top: cannot read nswapmap: kvm_read: Bad address
   top: cannot read swdevt: kvm_read: Bad address
   top: panic: nswapmap goof

When configuring the OS, the Configure script says:

   What module is appropriate for this machine? netbsd10
   Originally written for BSD4.4 system by Christos Zoulas.
   Based on the FreeBSD 2.0 version by Steven Wallace && Wolfram Schneider
   NetBSD-1.0 port by Arne Helme

It seems the NetBSD support for top hasn't been updated since
NetBSD 1.0 although the memory structures changed with NetBSD 1.3
(top worked perfectly on NetBSD 1.2).  Any plan to update this?
