That seems unlikely, since in Loom stack frames are carried by
fibers, and fibers freely circulate across threads.  The implication
of this is that fiber mount/unmount would have to push display
information into static thread locals; if there are N of them (statically
defined), then there is Nx as much churn for mount/dismount.
Seems like a dead end to me.
