r42Alpha3

I have been performing stress-testing on Magma for the last few days which has resulted in several fixes, performance upgrade, and functional improvements worthy to call "r42Alpha3".

I am getting really pleased with Magma r42 now because it behaving very much like a "industrial machine" during stress testing. Running 14 separate client "stressors", with server CPU at 100%, now maintains consistent memory utilization and performance, even after more than one-million elements added to a MagmaCollection in the test.

This latest configuration is now posted to the "MagmaTester" project of squeaksource.
