Is this safe with threads?

I'm looking rewriting a code example I found on the intarnet. Here is a quick run down.

threadMain main() creates a new thread (public STATIC pipeManager), this in turn creates ServerNamedPipe threads. Each ServerNamedPipe thread calls Form1.PipeManager.WakeUp(). WakeUp in turn calls Mre.Set(). (private ManualResetEvent Mre;)

Question 1: when WakeUp is called the method executes Mre.Set, is this run from the ServerNamedPipe thread or the pipeManger thread? (I'm 95% sure its SNP thread)
Question 2: The help states the MREs "Any instance members are not guaranteed to be thread safe". Does the Mre.Set() need to be be within a lock{} ?
Question 3: Or is all this OK as long as the pipeManager is a Static variable?

MRE /and the other common waithandles) are threadsafe by design. No need to worry, no lock needed.

Ok but what does the help mean when it says "Any instance members are not guaranteed to be thread safe" for MREs?

(and what about question 1 :)
