[Pkg] The Trunk: KernelTests-ul.233.mcz

[commits at source.squeak.org]

Levente Uzonyi uploaded a new version of KernelTests to project The Trunk:
http://source.squeak.org/trunk/KernelTests-ul.233.mcz

==================== Summary ====================

Name: KernelTests-ul.233
Author: ul
Time: 16 September 2012, 8:17:11.75 pm
UUID: 6a2da463-10c3-7e46-9c87-69204b8d1163
Ancestors: KernelTests-ul.232

Speed-up for CompiledMethodComparisonTest >> #testHash:
- instead of comparing all methods with all other, only compare methods which have the same size and header
- only compare each pair of methods at most once (assuming #= is symmetric)
It now takes less than 30 seconds using the interpreter VM on a 4 years old notebook.
Also added a progress bar and decreased the timeout.
