Due to the way httpd uses memory pools (which imply the data being owned by the current thread), such race conditions are probably very rare in most parts of httpd. The only likely candidates are the MPM modules. But the APR library is more likely to have such issues. Both MPMs and APR had bugs due to data races in the past (look at the commit logs), but I don't know if any of those are related to cache- consistency. Cheers, Stefan
