   I think there is a **slight** chance this one will affect some production 
deployments. This means that of the triggerer gets SIGINT (Ctrl+C) it **might** 
not close cleanly in the current versions of CPython. This is not likely to 
happen normally when Airflow run in unattended way (usually in such cases 
SIGTERM is used to terminate processes not SIGINT). But we cannot exclude it 
and also it makes it not really nice for any kind of debugging and manual 
running of airflow components.
   
   Maybe (@andrewgodwin @ashb @dstandish WDYT?) we could add some protection 
for that (if we all agree this is a likely reason) - I think that triggerer 
could simply add a custom SIGINT handler which would exist immediately, rather 
than print Keyboard Interrupt printing ?
