The problem there is that the debugger for the 1/0 is opened when 
Morphic ends the current cycle, to reduce risk of breaking state. But 
the Delay runs in the same doit evaluation, in the UI process won't end 
the current cycle until the doit is completed.

Just pushed a fix, that briefly forks a kind of watchdog process, and 
spawns a new UI process if the debugger takes too long to open. Please 
review.

Thanks,
