10GB of RAM isn't that farfetched nowadays.
However I/O might be a problem. A single drive can typically write/read
about 10MB a second (64KB chunks random access - not sure if you'd want
to bet on getting sequential throughput ;) ).
Anyway, it'll be something interesting to see ;).

The database server is started now with max_connections = 10000
and 100MB RAM is used
/dev/sda:
Timing buffered disk reads: 162 MB in 3.04 seconds = 53.32 MB/sec
It is not that bad :)
Yes I know there should be more disk arms.
Now I'm curious to see how the many threads will be handled in Java ...
