eivind(bitbox)--% glimpse NFS_MUIDHASHSIZ
/sys/nfs/nfs.h: #ifndef NFS_MUIDHASHSIZ
/sys/nfs/nfs.h: #define NFS_MUIDHASHSIZ 63      /* Tune the size of nfsmount with this */
/sys/nfs/nfs.h:         (&(nmp)->nm_uidhashtbl[(uid) % NFS_MUIDHASHSIZ])

Looks like it would be better off as 32 to me.

BTW: Would it be a good idea to have a page in the handbook describing
'a good kernel development environment' or 'tricks and tips for the
kernel developer'?  I know I have a few tricks up my sleeve, and I
assume others have, too.
