An ugly workaround could be to start clearing one of these fields,

(I said it was ugly...)
Or we go back to stashing a flag in uc_flags (which is kosher),
and try to figure out how to mark non-rt sigframes.
Or use the OSXSAVE hack. Let me think about this for some time.
There is also the option of simply using a field guarded by a 64- or
128-bit magic number. It's a bit ugly, but it works.
