I also don't think RAMFile should be public, ie, the only way to make
changes to a file stored in a RAMDir is via RAMOutputStream. We can
do this separately...
{quote}
RAMFile's public ctor without directory is only used by PrefixCodedTerms,
itself used only by FrozenBufferedDeletes. I don't really see the real use case
to do this like that. We can maybe replace that using a FST (it is already
sorted by BytesRef) or using PagesBytes? Alternatively replace the whole thing
with OutputStreamDataOutput(new ByteArrayOutputStream())?
