Likely also by comparison to FreeBSD 5 directly after it, which introduced concurrent kernel entry (instead of a single giant lock) and was considered somewhat buggy for a while. Or so I am told.
5.x was extremely buggy and unstable. It got usable around only after 5.4 release.
5.x wasn't just the removal of Giant Lock, but also:
- GEOM
- Kernel Scheduled Entities
There weren't any reasons to switch from 4.x to 5.x until 5.x got stable. Even with Giant Lock given the hardware at the time (Pentium with hyper threading) it wasn't that bad.
