Originally this used both SolarMutex and an own mutex, then a deadlock was resolved in 2fe6a4a34b38c05e252c71f4d2f18e4a90e61b29 by not locking SolarMutex. Since the class will call event listeners without dropping the mutex e.g. in insertNoCheck(), using the SolarMutex appears better anyway. With this, installing a BASIC extension no longer triggers SolarMutex asserts in SfxBroadcaster. Change-Id: Ib9a2ee491ef53b1a53855af0fc22e863c5e7cb91
