 i ran anita against i386 recently with the default of 32
 MB ram and i got a crash while extracting sets:
 
     Command: progress -zf /mnt2//i386/binary/sets/base.tgz tar --chroot -x=

 i realised that with the 21MB /netbsd GENERIC, there is
 even less ram available now than 0.9 days and 16MB ram,
 as the kernel wasn't even 1MB:
 
 [   1.0000000] total memory =3D 32252 KB
 [   1.0000000] avail memory =3D 10076 KB
 
 
 so we're already well beyond 32MB minimum needed.
