Hi, LOG4NET-164 introduced a new locking strategy for FileAppender which technically uses a System.Threading.Mutex with a name built from the log file's name. This should allow separate processes to share a log file without repeatedly opening and closing it.
The main remaining issue is its name (apart from docs which will follow once the name is settled). Right now it is called MutexLock but that may not convey to users what this actually does - they'd need to know what a Mutex is in the first place. I'm notoriously bad at names so I'm asking here now. Names suggested in the JIRA ticket are "InterProcessLock", "SystemWideLock" and "GlobalLock". Stefan
