Well I have no confidence in my power supply or Linux, and I'm not sure how I would get pg to run on a ram disk anyway, but I also thought that you had to run Linux in a special mode to force it to write to the disk before it reports success.
Also the ACS no longer returns multiple ns_writes per request. Even if you see these in the code, most requests are handled by the abstract url registered proc. I have replaced this with my own filter that lets you tune a little bit how much gets returned at once, but ARSdigita is now saying high volume sites cannot waste their time with multiple returns.
When I do more testing with extra ram and a bigger cache, I'll report any success or failure here.
