here is excellant intoduction to NetBSD-5.0

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
$ ./ -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
