OK, here's the correction.

You call swapbuffers and it simply isn't going to happen until
everything is drawn so blocking in SW is little difefrent from
blocking in HW provided the transport delay of a swap call is
small which it is. The key question is "can I do usefull
gfx work after my call to swap but before HW swap", the answer
is no, the pipe blocks almost immediately, hence swapready isn't
essential.

Cheers,Angus.
