I have also been having problems that I think are caused by the RAM cache.
Does anyone know what it actually caches, and whether it's write-through?

Several times I've had the machine crash and rebooted to discover that files
I had saved weren't there any more.  If this is because they're somehow being
cached until some later time, this means that the RAM cache is very dangerous.

It's nice to get the speedup the cache gives, but not at the risk of losing
files (or corrupting the disk directory).  Does anyone know if there is a safe
size to set the cache that will prevent this?
