[Vm-dev] CogMT

[Marcel Taeumel]

Hi all!

Here is a rather broad question: What is "CogMT" about? For whom are those multiple threads (MT)? :-)

The only build configuration I can find is build.linux64ARMv8/squeak.cogmt.spur. There is an issue with the type of sqOSSemaphore. That got me interested in the idea of CogMT ... which predates ARMv8 by a lot, right?

Best,
Marcel
