Hi Michael, thanks for the patch, it looks good to me. I have two questions: do you think that the creation of a new election object won't be
interfered if the old object shutdown/GC hasn't happened yet ? and any way to test this using a unit test ? Since you're doing
stress tests I'm less worried if a unit test is complicated. You'd probably have to somehow suspend a messaging thread to create
the deadlock, not sure.
