Yeah, it would reverse the problem from "how to share data" to "how not
to share data".  We'd want to find a way to ensure that the bulk of the
static data becomes per-thread data (or, in some cases, add a mutex so
that multiple threads can safely share one copy).  It won't be a trivial
bit of work, but conceivably it could be less messy than trying to store
and reload many of those same variables.
