Test new sync server API hanging: #383

def init_if_not_running():
global _KALEIDO_INITIALIZED
if not _KALEIDO_INITIALIZED:
print("initializing Kaleido")

_KALEIDO_INITIALIZED = True
def test():
print("I'm being triggered")

atexit.register(test)
init_if_not_running() # comment out to exit gracefully
Then later, when trying to terminate via exit() or quit or Ctrl+D, it will hang. Notably, it will not even print "I'm being triggered" from the other registered function.
But when init_if_not_running() is commented out, it successfully calls the registered functions.
