Taking crafty.  The typical speed I see is 2M-2.5M nodes per second on
this dual xeon box.  let's take 2.0 as easier to multiply with.  A
hash entry for crafty is 16 bytes.  Crafty doesn't probe the hash table
in the q-search, so let's assume that is about 1/2 of the total nodes
searched.  So we are going to need to store roughly one million entries
per second, or 16 megabytes.  If you want to search for 100 seconds, you
need about 1.6 gigabytes.  If you want to search for 5 minutes, then
about 5 gigabytes.

You get the rough idea...
