We had discussion on reasons why cmd+. is not always working.

I made simple test which shows that VM is not issue. Following code normally stops after 20 seconds:

hanging := [1 seconds wait. 1 recursionTest] newProcess.

hanging priority: Processor activePriority + 10.

interruptor := [ 20 seconds wait.��hanging��suspend] newProcess.

interruptor priority: Processor activePriority + 11.

hanging resume.

interruptor resume.

Recursion method:

Integer>>recursionTest

�� self��recursionTest

Hanging process produces 7 million contexts on my machine:

c := hanging suspendedContext.
count := 1.
[ c notNil ] whileTrue: [ c := c sender. count := count + 1 ].
count ��7395279"

But if you try to debug it by "hanging debug" you will see how it is slow. It's caused by printing stack to file.��

Interesting that logging is performed before opening debugger. So every time we press cmd+. we are waiting logging to see debugger.

We need to change this logic.��
