Yes. But that forked process is waiting on delays almost all the time,
and needs to wake up and do its stuff precisely at the start of a new
second. In Squeak, it runs at priority 40, so this is not guaranteed. I
suggest doing this change in Squeak too. Besides, I added protection
from invalid offsets with the OffsetsAreValid class var. In a commercial
project, I found that with the Squeak implementation, using DateAndTime
during system startup is not safe.

Right. I did not remove #detect:ifNone: as that would break a lot of
code. But I believe having the actionBlock in the sender will usually
save some #ifTrue: to do stuff only when an element was found.

Cuis change sets are numbered and should considered in order. Latest
update number is 034, so 431 is quite old. It is actually older than Cog
public release. That code was modified later, when the issues you
mention were found in Squeak. You can check that by opening a changes
list on change set 431 in Cuis. MessageTally works correctly in Cuis on Cog.
Thanks for reviewing!
