[Zope-DB] 2 sql methods issue (was Re: SQL Relay)

I am currently struggling to contain the damage this issue has caused at my company. Anyone
stumbled onto a resolution yet?
it may be interesting - or old news - to note the following findings:
I've tried splitting the zope-based services we run onto two separate zope instances, on the
same server, and unfortunately even in this case zope2 will not serve any requests while zope1
is using more than 1 database connection actively (note - i have found that any action involving
a zope db connection, not just a sql method, will cause this hogging situation). However, while a
hogging situation is in effect, I can run hello.py against the same python bin, from the command
line, which returns results without any delay. I am now trying to get my sysadmin's help with a
test running the zope instances against distinct python executables.
If anyone out there has found a way out of this mess in the past weeks, or can show that this
behavior is by design (and how to override!), I'm truly all ears.
