As was already explained in haiku-development (see discussion about
Terminal clear behaviour from 5 March 2013), Haiku version of top command-
line utility is not perfect in information output. The problem is that
every teams information snapshot is pushed into Terminal history instead
of overwriting it inplace as other OS' top implementations do. The source
of problem is Haiku Terminal implementation of the "clear all" command
(\E[2J) - it just fill the screen with empty lines pushing old ones in the
history.
Possible solution can be refactoring Haiku top to use alternate screen
buffer technique instead of normal buffer that is used in current top
implementation. That is the way other top implementation go.
