According to this they never had a concurrent or incremental GC
on x86.
Sorry about the caps, couldn't find a better way to emphasis. Not
sure where you found out the information about x86, or why it
should matter.
"The current collector is, by default, INCREMENTAL and
GENERATIONAL. The interruptions of service should be very small,
and the overall performance should be better than with the
previous collectors."
"Note that the new optional BACKGROUND collection THREAD is not
on by default; this may change in the future."
I take this to understand that the latest collector was
incremental, with the ability to work concurrently when the
background collection was enabled, on some CPU architecture,
regardless which one.
Modula-3 died when its team kept changing hands between DEC,
Olivetti, Compaq and HP.
It hardly had any new development since 2000, its GC would surely
look differently if development hadn't stopped and maybe even be
quite good on x86.
