-> debugger.set_trace()Now have some fun:
from guppy import hpy
hp = hpy()
heap = hp.heap()
heap.get_rp()To print the stacktrace across all the threads:
import sys, traceback
for thread_id, stack in sys._current_frames().iteritems(): print 'Thread id: %s\n%s' % (thread_id, ''.join(traceback.format_stack(stack)))
