Due to timing problem, test was not properly testing.
What needs to be ensured is:
vgdb is attached (i.e. is ptracing valgrind)
2 sigusr1 signals are sent while vgdb is ptracing
vgdb will queue these signals
when continuing, the queued signals are delivered.
With 3.9.0, the above causes an internal error in valgrind:
valgrind: m_syswrap/syswrap-main.c:1436 (vgPlain_client_syscall): Assertion 'sci->status.what == SsIdle' failed.
It would be better to have explicit synchronisation in the test
rather than counting on 'sleep xxx' to have things done in the
order that tests the signal queueing.
