Can VM handle two callbacks in parallel? No? Case closed :)
I just don't like that in certain scenarios VM will serve as a

Igor,

there are cases where foreign callbacks are needed and where this has nothing at all to do with performance or multi-core processors. I have already pointed out the case of monitoring a Java VM from a Smalltalk application which uses Java libraries. In this case, it's completely irrelevant what the performance is or whether the Smalltalk VM can handle two callbacks in parallel.

Best regards,
