It is not supposed to do:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
MessageTally class>>spyOn: aBlock
"
Spy on aBlock, in the current process. Can include or not statistics on
other processes in the report.
[1000 timesRepeat: [
100 timesRepeat: [120 factorial].
(Delay forMilliseconds: 10) wait
]] forkAt: 45 named: '45'.
MessageTally spyOn: [10000 timesRepeat: [1.23 printString]]
"
^self spyOn: aBlock reportOtherProcesses: false
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
I am not very familiar with the threading mechanism in Pharo, but since
factorial does not explicitly give the hand to other threads, how can other
threads be activated while the factoring is being computed?
Cheers,
Alexandre
