Modified Files:
        syssrc/sys/miscfs/genfs: genfs_vnops.c

Log Message:
fix two problems:
 - when yielding the cpu while using the vnode's page list, use a marker page
   to keep our place in the list (like the other cases where we drop the lock).
 - wait until no one else has the page busy before deciding if the page needs
   to be cleaned.  a page will be dirty while it's being initialized but will
   be marked clean before PG_BUSY is cleared.
