CountCallers

This is a test of the countcallers option.

t = TestExec()
trace = Trace(countcallers=1)
try:
    trace.run('t.run_this_and_that()')
    print "COUNTCALLERS"
except NameError:
    print NameError

<type 'exceptions.NameError'>

COUNTCALLERS

Once again it seems to disable the tracing.
