pix_share_read crashes on render()

[avilleret]

a call to shmat(shm_id,NULL,0666) on each render cycle doesn't seem to solve this issue
see my commit [1] in my branch fix_pix_share_read

calling shmat() in each render cycle is almost certainly a bad idea esp if you don't call shmdt() as well: as i understand it shmat() will increment the reference counter, thus leaving you with un-freeable chunks of shared memory.
