Does the "catch syscall" approach work when the exit is due to a signal?
I would have thought not, but I did not test it.
"catch exit" works via PTRACE_O_TRACEEXIT.

We go back and forth about the utility of it, FWIW.
I wrote most of what I did just to learn more about infrun and the
remote protocol; then one day we found some actual use for it :-)
