Ouch. That'd be really good. Do you remember finding any useful backtraces? > Nonetheless, I would be glad to test any patches you come up with.

Yep. The added instructions on the new Intel chips should make a dent though :-) -- Craig Ringer ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
