Build : JDK1.2.2 'M'
machine : orange
OS : 2.5.1, 2.7
bit depth: 8bit
applet : Traffic {/net/tapas/export1/java2d/Testing/applets11/traffic}

When 4 cloned appletviewer of traffic is run looping for overnite. SEGV *may* the result on 2.5.1 and on 2.7 there seems to be a tremendous memory leak. An overnite run will result in massive disk swapping.

Steps:
   1. launch appletviewer traffic applet
   2. clone it 4 more times
   3. tile it over the desktop
   4. let it run overnite (unsure of how long before SEGV)
