In order to process events in the order they are received for a
given device and therefore prevent multiple updates on the same
device from occuring in parallel (specially across cores - within a
core these are controlled via semaphores), we are letting an event
(mostly an update to a device) to run through completion. This
therefore prevent the adapter to send changes to a device in
quick succession while the update is being processed.
