[Zope-dev] Tracking memory leak

[Andy McKay]

Any chance you could clarify what SQLAlias does, ive definitely got the case
where some sql queries (and the way they are handled / used) causes an
increase in the SQLAlias count and some dont. Id like to find the quick work
around so I can get around to testing ZmxODBC

Cheers.
