Why do you say that I am upset? I am just pointing out observations.As it turns
out I think that WIN 95 does about the same job as WIN NT when allocating memory
to its cache. Because it grabs about 20Mb for itself, this has a large negative
effect on large hash tables on machines with 64Mb of RAM or less. Because of
this I recommend that all computer owners have at least 128 Mb of RAM in their
machines. With that amount you can allocate up to 90 Mb ( maybe only 64 Mb
because of block hashing)  of RAM without swapping.
