Hi.


On my EM64T machines wit SuSE 9 and SuSE 10 I can't reproduce crash.
StackTest and FinalizerStackTest return FAILED status.


Frankly speaking any tests crashed VM on my EM64T machine without "unset
JAVA_HOME". With "unset" all tests work, but .as I said StackTest and
FinalizerStackTest return FAILED status.


I try to fix of guard page creating on the EM64T thread stack as for ia32.
StackTest and  FinalizerStackTest start work and return PASSED.

But  gc.Force and others became fail. The source, as I understand, is in
following: after mmap of  the stack, java method Object.wait() can't works.
 SuSE 10 hangs up, SuSE 9 makes exit on it

In HARMONY-2224 <https://issues.apache.org/jira/browse/HARMONY-2224> I
excluded failed tests from acceptance test set:

    StackTest & exception.FinalizerStackTest on EM64T

    gc.LOS on Windows.
