When running
../../../bin/appletviewer -d64 -J-Xcomp example1.html
or
../../../bin/appletviewer -d64 -J-Xmixed example1.html

in the B69 on SolSparc8, I get the following warning
      
Java HotSpot(TM) 64-Bit Server VM warning: Attempt to protect stack
guard pages failed.

and the system runs very slow.... almost hangs

To reproduce the problem please run the attached script from the $JAVA_HOME/bin directory in B69.

Also you can reproduce the problem by following steps
1) cd $JAVA_HOME/bin
2) /net/sqesvr/export/vsn/GammaBase/Bugs/4473094/doit
