[Zope-dev] zope 2 and non-multithread safe extensions.

How should a Product that's not thread-safe indicate this to Zope 2? Say, for the sake of argument, that I had an (unreleased) SNMP product that wasn't thread-safe. How will this play in Zope2? Will the entire thing wedge on the SNMP product while it's doing a call? Or will it just block a subsequent call to the SNMP product? BTW, the Zope table-type objects (as seen in ZSQL results) work rather nicely for SNMP tables. :) Anthony
