Summary: assertion failure in thread stack scanning

Initial Comment:
running t3GT3 (component of jni tests).

Suspect problem is caused by last MMTk refactor.  t3GT3
is a test that trigers a GC while one of the threads is
in native code.

This is a regression.  It is now failing on all
configurations all of the time.  Before last week it
was working on all configurations.
