Marcel Taeumel uploaded a new version of Kernel to project The Trunk:

1) Restart timer-interrupt watcher process during system-wide clean-up.
2) Extract idle-process into own method because that's what we usually do: EventSensor (interrupt watcher), EventSensor (event tickler), WeakArray (finalization), etc.

That looks very good, thank you for cleaning it up.

Should the changes go into the squeak52 stream also?

Dave

Backporting ReleaseBuilder into the squeak52 update stream requires
adopting the four changes in ReleaseBuilder-mt.194, while skipping the
other changes in 191, 192, and 193.

In order to prevent file name conflicts between trunk and squeak52,
I propose saving the new version in squeak52 with the name
ReleaseBuilder.merge-XXX.191, and making a new update map to point
to ReleaseBuilder.merge.

If there are no objections I will make those changes soon.

Dave

Done.

The ReleaseBuilder update is ReleaseBuilder.merge-dtl.191 and the
update map is update-dtl.437.mcm.
