Um, two fallacies:
1) You can allocate as much shared buffer ram as you want. The maxium I've
tested is 300mb, personally, but I know of no hard limit.

2) However, allocating more shared buffer ram ... in fact anything beyond
about 40mb ... has never been shown by anyone on this list to be helpful for
any size database, and sometimes the contrary.
