No, that's the wrong way around.  A concurrent GC might be needed at
some point in order to help STM.  But you don't want to write a GC
*using* the STM features.  Instead we need to write a GC taking STM
into account, and probably sharing the same read/write barriers; if
anything, it makes the job harder than "just" writing STM or "just"
writing a concurrent GC.


A bientôt,

Armin.
