Looking at the JS stack we print out now right before the assertion:

IIUC we come from this timer which can be started with GMP_CHECK_DELAY == 10s. I think it is reasonable to assume that the callback needs to check if it is still desirable to do anything once the timer fires. Or we need to cancel that timer in time (by an observer).

Ups, we already extracted this case.
