NetBSD 5.0 looks cool

[Masoom Shaikh]

here is excellant intoduction to NetBSD-5.0

http://www.netbsd.org/~ad/50/img0.html

certain statements are very impressive in those slides like "Build any
NetBSD platform from any POSIX environment"
$ uname -s -m
Linux i686
$ cd netbsd-src
$ ./build.sh -m sparc64 release

develop and test 32 bits apps on 64 bit env
cc -m 32

does FreeBSD has those two features ?

also can anyone comment about locking granularity in FreeBSD kernel
