-// This used to deadlock with the old libstdc++ because there is only one
-// global mutex guarding initialization of statics and it is held during by
-// the initializer thread of a static until the variable is completely
-// initialized. If the initializer thread creates and waits for another thread
-// which also initializes a static variable, there will be a deadlock because
-// the first thread is holding the mutex and waiting for the second thread,
-// which is blocked when it is acquiring the mutex.
