Sorry I not too careful watch this discussion, but if I see thatyou are talking about PostgreSQL memory management and
threadsI have have a note.
 
I and Dan Horak one year work on Mape project (http://mape.jcu.cz) and we already have ported good postgres memory
managementinto thread daemon. It works very well and it's transparend solution -- you not must rewrite routines that
useMamoryContextSwitchTo or palloc() and other stuff, because everything is based on thread-specific contexts (see man
aboutpthread_key_create). With this solution you not must change to muchthings in current code.       Karel
