I know there are some fixes likely to be in Zope 2.6.2 that may help with the situation, but I'd like to put extra protections around this code regardless of what may be coming in the future.
It will only get worse with 2.6.2: the number of conflict errors cause by the sessioning machinery in 2.6.2 is going to go up as compared to 2.6.1 and below. This is because the strategy used to reduce the number of conflict errors used currently causes data desynchronization problems.
A while ago I experimented with ways to prevent conflict errors from reaching the application. ZODB has matured since then and it should now be possible to make a Connection class that resolves conflicts internally rather than propagate them to the application--as long as the application follows certain rules. Should we consider finishing that effort? Relevant URLs: http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/zodbex/zodbex/Shield http://dev.zope.org/Wikis/DevSite/Proposals/ArmoredCatalog Shane
