Raise a warning and avoid blocking GUI if some meta/macro/etc. get into an infinite loop #1806
Description
Is your feature request related to a problem? Please describe.
my plugin plover-run-shell can be accidentally used to run something that blocks forever like sleep 100, this will make the GUI unresponsive
Describe the solution you'd like
raise a warning if a single command takes say more than 1s to be processed (don't think it's possible to do much about it other than killing Plover though)
(should work as long as the GIL doesn't get taken)
Describe alternatives you've considered
Additional context
first encountered when a xdotool windowmove freeze for inexplicable reasons.
