Then close it. It will crash. I added some debug in StorageManager.cpp:
createLocalStorageMap: this=0x7f5afcfee3c0 storageMapID=1 storageNamespaceID=1
addListener: this=0x7f5aa7ba9150 storageMapID=1
createSessionStorageMap: this=0x7f5afcfee3c0 storageMapID=2 storageNamespaceID=3
addListener: this=0x7f5aa7ba9230 storageMapID=2
createTransientLocalStorageMap: this=0x7f5afcfee3c0 storageMapID=3 storageNamespaceID=1
addListener: this=0x7f5aa7ba93f0 storageMapID=3
createSessionStorageMap: this=0x7f5afcfee3c0 storageMapID=4 storageNamespaceID=3
addListener: this=0x7f5aa7ba94d0 storageMapID=4

addListener: this=0x7f5aa7ba94d0 storageMapID=5

ASSERTION FAILED: m_eventListeners.isEmpty()
../../Source/WebKit2/UIProcess/Storage/StorageManager.cpp(180) : WebKit::StorageManager::StorageArea::~StorageArea()
So the problem is the listener for the second session storage map (storageMapID=4) is not being removed.</pre>
