They've been re-arranged, but not randomly. What actually happened is the
yard crew ripped out the decks all the way down to the keel and replaced
it with a catamaran and now the deck chairs are in different places
because the decks are in different places. BSD was unchanged for 20
years or because nobody else undertook the work the SMPng team has done.
Recall this is the work that even might Sun punted on, preferring to go
help AT&T rewrite the guts of SysV.

You have verified that your interrupt twiddling and such doesn't hose SMP
machines, right? You really must understand that support for modern
machines is much more important to FreeBSD than supporting some ancient
junkpile CD-ROM device.
