/usr/bin/who shows logged-out users

["Thomas R. Shemanske" <trs@hecke.dartmouth.edu>]

Recently I have noticed (legitimate) users logged in on one of our
servers with no processes running.

I know for a fact that they log into the server via (open)ssh, and
eventually close the ssh connection.  These are all current potato
systems with 2.2.17pre6 as kernel.

Nonetheless, <who> still shows them as still logged on (as does <last>). 
On the other hand, <w> does not show them as logged on.

Is there a way to get /var/log/wtmp to update itself?  Any ideas what
the cause of this might be? (ssh shutting down impoperly?)

It's not a huge problem, but an annoyance.

Thanks for any input

Tom
