Because the length of the grab would depend on a timeout, we should probably use a GrabModeSync pointer grab and XAllowEvents with SyncPointer so that we can ReplayPointer to send events that are not part of a scroll transaction to the right window.

GDK doesn't support synchronous grabs so we'd have to use Xlib directly.
Starting a GrabModeSync pointer grab asynchronously with XGrabPointer may work OK. XGrabButton could be used to start the grab synchronously on ButtonPress, if necessary.
