Description of problem:

left running long enough the command 'top' output eventually disappears.

the cpu and meminfo content at the head of the window remains and is updated but
all of the process information either goes away or becomes invisible after a
couple of minutes of refreshing.

Version-Release number of selected component (if applicable):

procps-3.2.7-6

How reproducible:

always happens - just a matter of the number of refreshes/repaints of proc info.

Steps to Reproduce:
1. xterm or gnome-terminal (happens in either)
2. run top
3. shift-p to sort by CPU util and 'c' to show command line
4. let poll and refresh - walk away - come back and see process info is missing
  
Actual results:

invisible proc info.

Expected results:

visible proc info.
