This would slow down the fastest implementation of promises we could
hope for by an order of magnitude, at least on non-Intel platforms.

This in turn would severely limit the set of applications for which
SRFI-45 promises and SRFI-41 streams would be efficient enough to

If most of the Guile community wants to persue this strategy of building
thread synchronization into primitives that could otherwise be extremely
cheap, then I'd better withdraw from this community.
