There is a race condition in calling signal.signal() if the signal arrives while (or right before) signal.signal() is being executed: the function signal.signal(sig, action) marks the signal "sig" as not tripped. Because of this, signals can get lost. Instead, it would be better to call PyErr_CheckSignals() to check for pending signals. |
