I am trying to use the 6.0m9 remote pack. My IDE is on Windows, and my
application to profile is on Linux 2.4.21-138-smp, an older Suse. 

When I attach to the application and start its normal work, there is a flurry of
class loads from __VM_RedefineClasses__, then the exception shown below happens.
 At this point both the application and the IDE back on my Windows box are
frozen  and must be killed.

I may be able to provide a simple test case if necessary.
