[Lindenmaier, Goetz]

Hi Vladimir, 

thanks for the update.  Martin is currently preparing the contribution of the C1
on ppc.  In case we pick up the issue, we will ping you and Roland.

Best regards,
  Goetz.

Hi Goetz

Note, this problem occurs only when JVMTI agent is used. So it is not 
higher priority for us. I look on code and I think we can optimize it. 
Martin also add notes about the code to the bug report.

The RFE assigned to Roland. You should ask him when he will have time 
for it. If some can help us ;) we gladly accept it.

Thanks,
Vladimir
