hard to debug multi-threaded tests

In Pharo 5, it was possible to do...

TestCase subclass: #Example

....etc

Example >> test1

crShow: Processor activeProcess priority printString;

tab;

show: Processor activeProcess name.

self halt.

crShow: Processor activeProcess effectiveProcess priority printString;

tab;

show: Processor activeProcess effectiveProcess name 

] forkAt: 39 named: 'TEST'.

...and when this was run, a debugger would show for the forked code 

and stepping through it would produce the following output...

39 TEST

39 TEST

In Pharo 71047, no debugger shows up, 

and you only get one...

39 TEST

I guess this because more cleanup of tests is being done,

but it makes it harder to debug multi-threaded tests when 

debugger can't replicate the way the code normally runs.
