Under some circumstances, an application that embeds visvis might want to delay
the creation of a widget object. For instance when the call to create a new
figure is not done from the main thread.
This was an issue when Robert implemented visvis for reinteract. We discussed
this at EuroScipy and the code to fix this seems limited and relatively clean.
Therefore we should look into fixing this in visvis, so that others may benefit
from it too.
