Unsynchronized cross-thread access to m_opaqueResponseToSizeWithPaddingMap
in CacheStorageConnection::computeRecordBodySize
rdar://177953125
Reviewed by Chris Dumez.
We add a lock and the related lock assertions to prevent unlocked access to
the map.
Given the potential locking that may happen for form data size computation,
we make sure to compute the response real size outside of the lock.
