Oops, I made a mistake decoding the registers...FPRs
are 64 bits each, not 32 bits!  Gotta go back and
re-examine the correctly decoded registers to see
what's different for real this time.  Thanks for
pointing out that stupid error.

I believe I am not losing any signals except for the
intermediate SIGTRAPs resulting from repeated single
steps (all but the last one).
