Bummer. :-/
Having now looked at the gdb.base/jit.exp test, I see that
we can easily reproduce this with:
gdb ---args ./testsuite/outputs/gdb.base/jit/jit-main ./testsuite/outputs/gdb.base/jit/jit-solib.so 2000
(It'd be nice to turn this into a check-perf test...)

Yes, sorry. I meant whatever code ends up "sending" a JIT_REGISTER
event to gdb.
Thanks,
