Is this correct?  I thought that even dbpool would not pool resources 
between different apache processes.  Thus having a 
one-connection-per-process (or two, or three, but some fixed number) 
rule along with an apache maxclients setting would tend to keep the 
database connections within an acceptable range.

If the max number of clients could be known, regardless of the number of 
apache child processes, that would be great.  However, that doesn't 
match my understanding of how it works.
