Thanks for debugging this, it is a really serious problem. Unfortunately it looks like it will be pretty difficult/painful to solve too, but we definitely need to solve it :-( I agree that it is serious problem, but I don't think we have a way out here. Dan, do you have an idea? (In reply to Michal Privoznik from comment #2) > I agree that it is serious problem, but I don't think we have a way out > here. Dan, do you have an idea? I don't know enough about the glfs api, but perhaps it is enough to open the connection in the main process and let the open handle be used in the child which might then only require read/write calls. |
