Comment 7 for bug 1420301

I agree that it should be configurable because as you say, it depends on user preference. But setting that delay to zero does not solve the problem of the disappearing indication.

To reproduce.
-Open inkScape 0.91
-Enable the button "Snap nodes, guides and handles".
-Create a horizontal guide.
-Go to Edit -> Preferences -> Behaviour -> Snapping -> Delay and set to 0.
-Close the preferences window.
-Select the rectangle tool.
-Move the cursor over the guide (without dragging).
-Note the popup "Handle to Guide".
-Do not move the cursor and after a second or so, the popup disappears.
