I found another problem of this patch.

I ran the libspe2 test 'test-ibox.elf' with many SPEs; i.e.
"make check-test_ibox.elf TEST_SPES=30".

This test iterates the following steps with specified # of SPEs:
   1. check the ibox status.
   2. read data from the ibox.

Of course the test can stall at the step 1 if the check is performed
via PS direct access and context switching occurs. However, if this
patch is applied, the test process (test_ibox.elf) cannot be terminated
by Ctrl-C when the process stalls. Without this patch, that is possible.

I could reproduce this problem on both of PS3 and QS20.

Thanks,
