For the first time ever I just tried "make regression-tests". Need I worry
about:

regress ===> sys/kern/lockf
fcntl: Resource deadlock avoided
fcntl: Resource deadlock avoided
lockf: ptrace: No such process
stop 0
...
FAILED

or

regress ===> sys/arch/i386/ldt
get_ldt: Invalid argument
Testing i386_get_ldt...
FAILED

? (First thing after a fresh cvs update/kernel build/reboot/world build)

Cheers,

Patrick
