We observed that some threads can reach deadlock-ish state after they have Invoked into a control's UI thread. When it happens they are all in a waiting for join or in sleep state for very long time, although there should not be any deadlock situations.
It seems this has something to do with multiple parent controls and with which control we invoked on. This should not make a difference, because we have got one UI thread (for MainWindow) they should wait for, but we have seen it does.
The solution that fixed this issue was to invoke on the MainWindow instead of various controls (see a4fe507adf ).
This changeset is changing all our Invokes to invoke into MainWindow
instead of a control itself. (MainWindow's UI thread is the only UI thread
all Control is using in XenCenter)
This changeset should be in place until we have found the root cause or the exact reason for the above.
NewAction to use the Action<ActionBase> delegate instead of EventHandler. Thus
there is no need to fire them with Empty or null EventArgs and on several occasions
we avoid casting objects in the event handlers.

The logic to determine which rows have to be added/updated/removed has been moved to a separate thread. This improved the performance as the UI thread is blocked only to refresh rows in the dataGridView.

Modified BuildList() method to remove and add dataGridViewRows only when needed (previously all rows were cleared and new rows were added every time BuildList method was executed).
