The nv_conditional_render piglits were sporadically failing. Moving the control flush from the write and placing it just before the read was sufficient to make the piglits pass a 1000/1000 times. The bspec says that the flush enable bit "waits until all previous writes of immediate data from post sync circles are complete before executing the next command" - the operative word being previous!
