>Description:
   When running a kernel with more that 32 pty's after opening ttyqe
   /var/run/utmp is not updated correctly:
   Note that I have ttyp0 through to ttyr5 in use, but who/finger/w does not
   indicate them, and where I to open another xterm the ttyr5 would be over
   written with an entry for ttyr6

>How-To-Repeat:
    Build a current kernel with more than 32 pty support and open up the 
    lots of xterms. If a user remotely logs in his entry is also not
    added to utmp.

>Fix:
    It looks like a hard limit in utmp is being reached? Work around, no
    idea.
