Ask Xlib for events before blocking on the display in x11graph.scm.

Fixes race whereby Xlib may have queued up events already before we
ask the OS about I/O on the underlying file descriptor.  This can
cause us to fail to notice an event until a second one comes along,
so that, e.g., a newly created window will hang until you move the
mouse over it or similar.
