Python-2.7: No SIGINT possible in while loop with locks -

-

i implemented while loop locks in python-2.7 (see example) handle 2 lists loaded values other thread each. code works, not handle sigint (ctrl-c) anymore. example:

while true:   lock1:     if 0 < len(data_buf1):       foo(data_buf1.pop(0))   lock2:     if 0 < len(data_buf2):       bar(data_buf2.pop(0)

what enable keyboard commands again?

update loop runs in main python process.
