use wmb to flush the wc cache

Running for a week now with this patch instead of the other one and have not seen cursor corruptions.

Well, today I had the 8-pixel-line curruption on a cursor and interestingly it survived cursor switches between enlightenment (colorful arrow - corrupted) and gnumeric (cell '+' cursor), but passing over claws-mail caused enlightenment cursor to no have corruption enymore.

Does the hardware store multiple cursors or somehow have multiple cursor buffers around which can get corrupted and remain corrupted (double-buffering on cursors)?
