ps, top and wtmp/utmp (ie w,last, etc) have user name limits.  For ps
and top, it seem to be the POSIX limit of 8 characters, while
wtmp/utmp have 32 characters as the limit (see
/usr/include/bits/utmp.h).  To avoid admins being surprised when using
ps and top, I would strongly recommend to avoid more than 8 characters
in usernames.

Happy hacking,
