Probably.

Since I can't see that we can possibly even get started on precise
gc in the next 6 months, I see no shame in saying: I don't know.
And I don't have time to seriously research/ponder the alternatives
at this point. I'm happy to collection suggestions, opinions, and
references, but we're not ready to design anything yet.

That is misleading. We intend to support mutliple run-times, including
preemptive threads, as different configuration options. The only
*currently* implemented thread mechanism is a simple cooperative
threading system (base on setjmp/longjmp), but we have ambitions
beyond that.
