I find the close() side to be more appropriate. I say this for two reasons: (a) looking at the close() calls as they are now it is obvious what the close() applies to and transitioning to a loop adds a layer of unnecessary indirection, (b) I do not think a loop is appropriate for the READ/WRITE define that just happen to be 0 and 1 ... there should not be an assumption about their underlying value.
