They are stored in every suspended thread's floating-point-
environment slot.  We cannot restore a band with suspended threads
anymore?  Not unless an fenv_t is identical (in size AND meaning) on
both host (dumper) and target (restorer)?

Actually, I can roll with that.  If we ship runtime/*.com, the
installer can spin up an all.com optimized for the hardware on which
it is installed.  Despite the lost portabimini, many machines will
still be able to swap bands... no?
