Hi Finn,
nice work!

Saved registers are restored from the stack before return from
__GI___wait4_time64 but we don't know which of the two wait4 call sites
was used, do we?
What registers does __m68k_read_tp@plt clobber?

Maybe an interaction between (multiple?) signals and syscall return...
depends on how long we sleep in wait4, and whether a signal happens just
during that time.
%a3 is the first register saved to the switch stack BTW.
That kernel does contain Al Viro's patch that corrected our switch stack
handling in the signal return path? I wonder whether there's a potential
race lurking in there?
And I just notice that we had had trouble with a copy_to_user in
setup_frame() earlier (reason for my buserr handler patch). I wonder
whether something's gone wrong there. Do you get a segfault instead of
the abort signal if you drop my patch?
Cheers,
Michael
