Git commit 29247d6d19c49a20c17ea414a0e108905712a520 by David Edmundson. Committed on 30/09/2015 at 11:08. Pushed by davidedmundson into branch 'Applications/15.08'. Don't modify member variables in another thread m_connectedEvents is modified in connectNotify which according to the docs will be called from the thread of the caller, not this. As it is read from our thread this risks calling a clash.
