No.

Eventually, we should improve the collector (or replace it with a
better one) to support incremental collection. Then, it would be easy
to use idle CPUs for GC work. Currently, though, if a GC is started,
then the GC has to complete before anything else can happen, so a GC is
triggered only by memory demand or explicit request.
