Length of wmesg for condvar?

[Paul Goyette <paul%whooppee.com@localhost>]

The condvar(9) man page states "The wmesg argument specifies a string of 
no more than 8 characters..." yet there is at least one instance in the 
kernel sources where we have a wmesg long than 8 characters!  In 
src/sys/kern/kern_module.c in routine module_init() we have

        cv_init(&module_thread_cv, "modunload");

There appear to be several other similar violations in various places:

        src/sys/arch/x86/x86/ipmi.c
        src/sys/arch/xen/xen/balloon.c
        src/sys/dev/isa/fd.c
        src/sys/dev/tprof/tprof.c
        src/sys/dist/ipf/netinet/ip_auth.c
        src/sys/dist/ipf/netinet/ip_log.c
        src/sys/dist/ipf/netinet/ip_sync.c
        src/sys/fs/nilfs/nilfs_subr.c
        src/sys/fs/nilfs/nilfs_vfsops.c
        src/sys/kern/sys_pipe.c
        src/sys/net/agr/if_agr.c
        src/sys/opencrypto/crypto.c
        src/sys/rump/librump/rumpkern/sysproxy_socket.c

Should these be changed?  Are there any adverse effects from having a 
wmesg longer than 8 characters?
