readerwriterlockslim

I'm writing a global error handler/logger for applications running in Windows Azure. When an error occurs in the application, a number of operations are performed that need to happen atomically. I need to prevent an error from being logged until the previous one has completed. Meanwhile, I want reads of the logs to occur as needed. My initial thought was using a Monitor/lock and lock only the error writes. That way the reads aren't inhibited at all. I was wondering though whether a ReaderWriterLockSlim would be more appropriate. I can't say I truly understand the value between one approach vs.
