+Summary: Remove lock(typeof(T)) pattern from libraries
+
+We need to remove the usage of the lock(typeof(T)) pattern
+from our libraries: it allows malicious users to deadlock the runtime.
+The pattern should be replaced with a lock on a static object field
+used for just this purpouse (note an object of type object should be used,
+not a string which has the same issues as typeof).
+Likely a tool should be developed that catches this and it should be run
+periodically on the whole repository.
+This is a good janitorial-like job for people who want to start
+contributing to mono.
