Normally, when the code finishes, the console writes:
Code done running.
Press any key to enter the REPL. Use CTRL-D to reload.
Pretending to deep sleep until alarm, CTRL-C or file write.
Woken up by alarm.
However, after several hours, you see:
Code done running.
Press any key to enter the REPL. Use CTRL-D to reload.
and the board is frozen, without invoking deep sleep.
