Write delay appears to be fixed @ 5 secs?

Still beta-testing on the only machine that FC still runs on. My other machine has been permanently locked out by FC 
I've been experimenting with the write delay (beta 0.3.0.0). Suppose I set it to 30 secs and issue enough writes to fill both the L1 and the L2 caches (L2 caches to to 3 GB of invisible memory).
No matter what I do, I can see by the flashing of the disk light that FC flushes its write buffers after exactly 5 seconds. After the first flush, no further writes take place.
The stats (especially the L2 stats) confirm this. The count of unwritten blocks suddenly and sharply drops after 5 secs.
Any suggestion? I guess I'm just overlooking something.
Thanks.
