How to run specific part of the SerialGC in a new thread?

[Ofir Gordon]

Hi,
Sorry for the late followup, thank you for the answer.
I looked at the WorkGang mechanism and it seems a little overkill for my
purposes, I only want to be able to split the task to a different thread
and wait for it to complete. From what I understand, in order to do this
with WotkGang I need to create a dedicated AbstractGangClass which will
need to include all methods of the scenario I'm trying to run separately..

Is it not possible to use pthread or similar libraries within the code? Is
there another way that doesn't require using WorkGang?

Thanks again
