At https://github.com/reufer/rpihddevice/pull/14#discussion_r1083466069
I posted an example of using an absolute variant of 
cCondVar::TimedWait(). The thread cOmx::Action() would perform some 
action every 100 milliseconds, and additionally consume m_portEvents as 
soon as events are enqueued by cOmx::Add() in another thread.
