Okay, how to move forward then:

a)

we keep track of alarms and we expire them on image resume? this will probably
require modifications to the image format? We use addDependent on Time to
save/restore the millisecondsClockValue?


b)

We just let each Delay expire after a image restoration? E.g. by a resume
handler that sets the expected millisecondsClockValue to 0 and then calls the
Delay.Timeout... signal handler...

different:
Looking at the code, it appears that Process signal: atMilliseconds can only
be used by one user on the VM?
