Hi Greg,

That's cool.  Played with it for a while longer, then found out that the
order that it was being called in didn't work very well as the select()
was executed after all the required sockets had been closed/ended.

So, it just meant a re-ordering of things, and it's now working alright.

Am just "fine tuning" this util, and it's looking to be pretty nifty. 
It automatically tunes local or remote PostgreSQL databases (currently
it's limited to the shared_buffers, sort_mem, and vacuum_mem
variables).  But it's a start.  :)

Regards and best wishes,

Justin Clift
