I'm running 5.99.15 amd64 kernel and userland, both built from sources 
that were current as of 2009-07-19 14:09:23 UTC.  A quick test here 
shows no noticeable delay:

{895} time eject cd0
0.000u 0.002s 0:01.79 0.0%      0+0k 0+0io 0pf+0w
{896} time eject cd0
0.001u 0.001s 0:01.78 0.0%      0+0k 0+0io 0pf+0w
{897}

I will confirm that, just as Iain reported, I get the following logged 
on the console for each eject:

cd0(viaide1:0:1): not ready, data = 00 00 00 00 3a 00 00 00 00 00
