Hi Jarosław,

python-mode.el developer here, just being interested.

AFAIU electric-indent-mode doesn't run a timer, cursor position alone 
would not trigger it.

Assume there is a command used from pos. Which? BTW the key alone 
doesn't tell enough, as RET and C-j changed binding recently. Reporting 
Emacs version will be useful.

Thanks,

Andreas
