[Mono-devel-list] Thread Safety Question

Why is code such as:
public sealed class DefaultAuthenticationModule : IHttpModule
static GenericIdentity defaultIdentity = new GenericIdentity ("", "");
void OnDefaultAuthentication (object sender, EventArgs args)
if (context.User == null)
context.User = new GenericPrincipal (defaultIdentity, new string );
thread safe when Microsoft's documentation states:
Any public static (Shared in Visual Basic) members of
this type are safe for multithreaded operations. Any
instance members are not guaranteed to be thread safe.
Based on the documentation how do I know what is and isn't thread safe?
Clearly there will be a lot of GenericPrincipals out there pointing at the
same GenericIdentity. Example code I've seen for working with the
GenericPrincipal isn't synchronizing access to the Identity so will such
code blow up?
