I presume that in this latter case there is no pause ... that pretty much
nails it. it's a race condition not yet catered for. a temporary
work-around that will catch most instances is fairly simple: change

  if (m_InitializeEvent.timed_wait(lock, t) == false)

to read

  if (m_BackendState == kUnknown && m_InitializeEvent.timed_wait(lock, t)
    == false)

this is not a 100% solution as it still leaves a race condition, but the
window is much narrower and ought to get you going in most instances until
it's fixed properly.
