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!
