Bug 1448476 is adding a mechanism to report alternate data output stream failures, due to large disk entries.
Currently, in case of failure, the bytecode cache will not recall any failure state and keep re-encoding on the next page-loads. The serialization requires some computation which has some page-load overhead (~10%) and some memory overhead as well.
In such failures, we should use the mCacheInfo to SetMetaDataElement and GetMetaDataElement as a way to record a boolean which would prevent future encoding of the bytecode.

This issue is not longer needed as the cache is storing Stencil (Bug 1601332) instead of XDR content, and Stencil is the result of the parser. Thus, there is a smaller overhead at trying to encode the content to be stored in the cache.
