Log:
Ported from trunk r51808. Fix for threading/interpreter exit/tasklet killing bug.  The test case was to have 10 threads launched with a time.sleep(0.1) in each.  This would cause the tasklet killing to have an access violation when it tried to move the tasklet to be killed before the main tasklet in the scheduling list, but the tasklet being killed was the main tasklet.  Now if this is the case, no scheduling ordering changes are made as it is not necessary anyway.
